Metal-Enclosed Switchgear

I have purchased many pieces of equipment from Maddox ranging from 1000 kVA transformers to 10,000 kVA transformers as well as fused and nonfused load interrupter switches. I am happy with the cost and the lead time which has been perfect for the fast paced schedules with tight budgets we have been facing. The customer service has been on the spot when questions arise.

Worked hard to meet my deadline. very helpful & knowledgeable.

Worked excellent, tech support was incredible with helping me figure out what I needed as well

We've bought numerous transformers from Maddox. Excellent service both before and after the sale. The rebuilt units are coming out looking like brand-new transformers. No surprise up-charges, no problems in shipping. Highly recommend!

Very responsive to inquiry, prompt shipping, protective packaging, on time delivery. Will be back!

Wonderful service. Very responsive, offered all the guidance, and really stayed on top of it (I mean, really did so - send at least 10 emails on confirmation, status of the order, invoice, delivery, instructions on how to receive etc). Shipping was lightning fast (to Dallas, Texas) and without a single issue (this is not the first time I ordered commercial equipment, and every time it's a hassle). I couldn't find the unit for the same price anywhere. Overall, fantastic. I wish all companies cared as much about the product they sell

Website was easy to navigate where I could order my own transformer with little assistance.

We had a customer who lost their primary transformer in the middle of the night. Maddox was able to get a temporary transformer on site in hours. They also rebuilt the damaged transformer in record time while no sacrificing any quality. We were able to install and power up the transformer with no issues. The transformer was phased properly and the rotation matched the previous transformer. I would recommend Maddox to anyone for transformer needs.

We worked with Maddox most recently to repair a transformer at our site. Cameron and the repair team were very communicative, professional, and understanding of our needs to get back online as quick as possible. We are very impressed with the level of service we received and look forward to working together in the future.

Very prompt delivery and service

We have used you recently a few times, and will continue to do so as needed, however I have had to go elsewhere many times due to cost of shipping from Maddox puts us over the top for quote, but other than shipping issue, you guys have been great, especially Gabe, very fast and knowledgeable . thank you for everything so far. Tony.

We are a solar installation company based in MA. We've used many suppliers and distribution partners, and none have been as good as the kind folks at Maddox. They deliver high quality products on budget, and more importantly, on time. We've had many growing pains, and Maddox have helped us along the way with more than flexible payment plans as well as delivery timelines that matched up perfectly for our projects. They've won our business for life and we'll continue to order from them for our commercial and utility scope projects.

This is our first purchase with Maddox. They were very easy to talk to. The representatives were knowledgeable and the shipment came sooner than expected for the shipment.

They made a recommendation to suit my needs at a good price.

This is my first time ordering from Maddox & you guys have been great! Stephen & Laura have been a joy to work with & made this the easiest purchase I've made in a while. It's good to find companies that make the buying process easy. I don't know if we'll need many transformers in the future, but I'll definitely be recommending you to our electricians.

This is a great company to work with! The customer service people are friendly and helpful and keep you updated; Especially Josh! He has just been great! :) The items ship so fast and are packaged very well. Fair prices as well. Will be happy to order from them again. Thanks

Purchased a step-up transformer from Maddox knowing nothing about them...These guys went above and beyond on top of excellent pricing. I honestly could fill this up with nothing but good things to say about my experience with Maddox. If I could give them 10 out of 5 stars I would.

Prompt service, Make ordering and verifying your needs so you get the correct part easy and friendly

Prompt and friendly service! Will use these guys again for next project!

Prompt and courteous service!

Price was good. It was delivered fast. I am happy with the purchase.

Placed two orders, fast deliveries, great communication! Looking forward to do more business with Maddox !

Our salesperson helped us to find a transformer that fit within our budget and met design requirement. Excellent service, clear communication, and quality product.

Ordering was easy and when I had a question the knowledgeable staff answered promptly and courteously.

Ordering through Maddox was painless and they shipped a 200lb+ Transformer to our door in 3 days when we needed it urgently. Thanks again!

Ordering was easy and item arrived quickly. I want to say thank you to the Maddox team.

Ordered transformers to use on our industrial equipment applications due to market shortages for our standard stepdown transformers. Delivery was incredibly quick and products look and operate without issue. Priced very well in comparison to other outlets - very happy to utilize Maddox in the future for our continued needs.

Ordered online, shipped very quickly. Great communication. Would recommend.

nice and easy transaction with good price and good delivery time

My company ordered a new transformer from Maddox. Kurt was an AMAZING sales rep that listened to all my concerns and met them all with solutions that fit our timeline. Dale pulled off a miracle in getting our shipment on the road and delivered not only at the exact time I requested, but 2 hours early. I cannot express how happy I am with this company. They made me look like a hero! Which is exactly what THEY were to me.

Maddox Transformer offered a great buying experience. They had the transformer I needed at a great price and shipped it promptly! I received it the next day and am happy with the purchase!

Made an Online order. Maddox was extremely helpful and was emailing me with updates on my order. They even called to make sure that I would be available to receive the transformer or if they had to delay the shipment, as I ordered closer to the end of the year I really appreciate the dedication they showed to making sure I got the product I ordered. The unit arrived and works great.

Maddox, your company is awesome !! very knowledgeable, great service and turn around time. thank you

Maddox website was easy to navigate, and showed what transformers were in stock. Luckily the step up transformer I needed was in stock, shipped within 24 hours, and was on my dock in 4 days. If you know exactly what you need, I would highly recommend Maddox based on my experience!

Maddox Transformers is a great company to work with... Circuit Breaker Sales in Florida has had great experiences with Maddox recently. Prompt responses to our requests and excellent work on reconditioning transformers. Very Pleased with Maddox and will continue to utilize them in the future.

Maddox Transformer is a reliable product and a highly professional company. Mac Spiller was very responsive and helpful with all my questions and concerns. His attention to detail and curtesy made my experience with Maddox over the top!

Maddox - Great company and great products, little slow on the customer service side in the beginning but increase 10 fold after Jassen started helping us get back on track and get us our 2- 2500KVA transformers. Will definitely order from them again, Thanks Jassen!

Maddox id a great company to work with for buying any transformer that you need. Super Fast Shipping and great communcation. Plus a great price!!!

Looked around hands down the best bang for the buck saved me over 1200 bucks from my supply house beers on me lol

Mac and his crew did an absolute fantastic job installing my transformer. I had a transformer fail due to the heat and age, but Mac quickly had a replacement for me at a great price. His team did a bang up job getting it on my site, so we could get it installed. HIs team saved me a week of downtime and lost product. We will be using them again in the future! Thanks from the team at Great Western Malting at the Port of Vancouver. -GWM Maintenance Manager

Great to work with!! Very knowledgable and fast service!! thanks!!

Its been a pleasure working with the Maddox Team. Equipment pricing is competitive and staff expertise is strong. Our initial purchase of 4 large Transformers has gone seamlessly. Considering we are engaged in a multi-year purchase of transformer replacements across our communities we remain confident that this project will continue to be successful due to our work with Maddox.

It was nice and easy ordering the transformer delivered in time I recommend Maddox strongly don’t look any ware else

It was easy to find what I needed and order through the website. After my order arrived, I had a technical question, and the support staff was knowledgeable and helpful. Overall, it was a great experience.

I wasn't sure what size step up transformer I needed. Called the tech support line and these people are great. Very hepful and friendly. Unit shipped following day after the order and arrived soon after. Great product and company. I highly recommend and will use them for future purchases. Thanks Maddox!!

In a post Covid world where nothing is available in the construction market, Maddox Industrial Transformer had what I needed. Reasonable price and fast shipping. Pretty shocked and pleasantly surprised to find a company that still values service and support. Thank you for your help.

I’m thoroughly impressed. The transformer arrived 3 or 4 days after ordering online. It was well packaged, and well constructed. I’ll definitely use Maddox the next time I need a transformer.

I'm a trucking company owner that delivered here. Nice new facility. Friendly, helpful staff. Easy to get to and didn't take long to unload. Hopefully I have the pleasure of ending up here again!

I would like to tell everyone what a great experience I had dealing with Maddox transformers. Every one that I had any contact with form sellin buying and warehouse was great.

I work in the Data Center space. We have well over 100 Maddox Transformers. They have preformed exremely well over the past two years. Customers service is always top notch. Highly recommend this company.

I will have to say that I was very impressed with the way you processed our order. We were provided updates through the entire process, from quoting to the delivery. I absolutely would recommend you to anybody looking to purchase or repair transformers.

I was very pleased with the quick response and shipping I received on a short timeline I had for the project I was doing.

I was very happy with the product, service, and delivery on time. Especially Josh long was helping me out deciding which transformer to use. I purchased a transformer 30KVA step down from 240V to 208V 3 phase. The transformer has 7 tap inside which you can choose or adjust exactly output Voltage. Our voltage input 252V, 3 phase with high leg 208V phase B. But our new machine need to run at 200-208 Volts. Thank you so much! super highly recommended.

I spoke with Josh Long and he was the most knowledgeable sales rep on transformers I had the pleasure of speaking with during my 2 month long ordeal to find a very specific transformer for my machine from overseas. I really appreciate his expertise on the matter and I look forward to working Josh again.

I ordered two transformers from Maddox within a week, both were for a trade show and both were urgent. The first was delivered to us in a 2 day timeline which was awesome, the second one we had our courier pick up from their warehouse and we had it next day. Transformers ran perfectly, excellent service from this company.

I ordered a transformer to go from my 3 phase RPC from 240 delta to 480v Y. There team really helped me with different options to suit my needs now and the future instead of just selling me what "they had laying around." As my needs grow, I will be a returning customer.

I love this company. I'm an electrical contractor and I use them for all my transformer needs and recommend them wherever I can. Josh Long and Chris Stouffer always return my calls and answer my emails. They provide a great, personalized service. It's nice to go straight to the source to buy rather than going through an electrical supply house or another middle man.

I called Maddox to order a transformer, I found them to be very helpful and they had the transformer in stock! It was shipped the next day. I'm very happy with their service!

I called for info on an item these guys don't even sell and Nick went above and beyond in helping me out. If that's how he's like with someone who's not even a customer of his then you can be pretty sure that if you did buy from these guys that you'd get superior customer service.

I am looking to purchase a step up transformer and started to read the reviews. Hats off to you Maddox for your efforts and responses to all the reviews. I look forward to working with you!

Had an issue with shipping scheduling. Shipping manager called me directly apologized and is compensating for the miscommunication. Said this is not how we normally do things . Super happy to see a company taking accountability and respecting truck drivers time

Have purchased two transformers from this company over the past year and they have exceeded expectations every time. Super fast delivery, easy to order and very helpful. would recommend!

great service, quick delivery

Great service and products. Gast shipping for large items.
