Electrical Load Calculation

Phoenix Contracting Services provides electrical service load calculations up to 400Amps, electrical one-line diagrams, electrical feeder calculations, electrical panel calculations, electrical fault calculations and electrical panel schedules as prescribed per the National Electrical Code NFPA 70.

We have an electrical designer and electrical inspector in-house to expedite your design and can help you obtain your electrical permit.

In addition, we also provide third party electrical engineering for larger projects upon request.

As a separate service, we aid in the collection of electrical data necessary for engineers to create reports for power monitoring, arc flash and selective coordination studies.

Whether it is a branch circuit, electrical feeder, or main electrical service, a good electrical installation should always have some form of approved load calculations performed and code conformity observed to ensure the electrical system design is safe and of sufficient capacity to carry the designed load.

What is an Electrical Load Calculation?

The purpose of an electrical load calculation is to accurately determine if the electrical service and its feeders are of sufficient capacity to carry the calculated load shown, whether it is on a residential, commercial or industrial project. The basis used is the National Electrical Code to ensure an electrical service is sized properly and installed correctly.

Why should I hire a professional electrician?

In the electrical field, there are many things that can go wrong, some of which are costly while others could be dangerous.

So as a rule, always check references such as Google or the BBB before hiring an electrical contractor. These professionals should be licensed, experienced and have the ability to clearly share any deficiencies they find in your electrical system.

Why Do I Need One?

As a woodworker aficionado, in my spare time I have built just about everything from wooden sailboats to kitchen cabinets, to furniture, to entry doors, and may even try building a guitar. I absolutely enjoy building things out of wood. So, when I say that Jeff and his crew are very competent, you can trust my words. They helped me build a workshop at our home. I am not a contractor, nor do I build buildings, but I know good workmanship when I see it, and I see it here. You will find them ...

I have been exceptionally pleased with the work done by Phoenix Contracting Services. It is consistently excellent. One of the best parts of their service is their attitude. It is one of wanting to do their best for you and to know what else they can do while they are there. They always offer sound advice and great service. And if they need to come back to finish something that they ran out of time to do, it is usually within 24 hours, something unheard of in this area.

Excellent Service! My air conditioner had stopped cooling and I called Phoenix Contracting Services and set up an appointment on Monday morning. The service man “Josh” was very knowledgeable and explained everything that needed to be done. I thought the main problem was the capacitor and I was right. He replaced it and serviced the equipment. I also told him that one of my son’s room was not cooling. He found that the air duct was split between two rooms, so he fixed that problem, too. He ...

Outstanding job! Phoenix Contracting Services is awesome. They came out on time and just provided us with top notch service. They installed an outside system and also did some major ductwork in the attic. Our attic is super tight and hard to work in but they were able to be up there working nonstop. Everyone was professional, accommodating, and worked on our house like it was their own. I’m so glad to have found them and would recommend them highly.

Phoenix Contracting Services, we wanted to thank you for your help in restoring power after the storm. In the face of an inane county inspection requirement from the power company, we weren’t sure how many hoops we were going to have to jump through. But you made the process as quickly and easily as we ever could have hoped. We greatly appreciate your professionalism, speed and compassion. Thanks again.
