"I am writing to express my sincere appreciation for the outstanding work performed by Diamond Electric during a recent electrical service upgrade at our property. From start to finish, the entire crew demonstrated professionalism, punctuality, and exceptional craftsmanship. They arrived on time, communicated clearly throughout the process, and completed the work efficiently and safely. What stood out most was their attention to detail—even the smallest aspects of the job were handled with care and precision. It’s not often that you come across contractors who combine technical expertise with such a strong commitment to quality and customer satisfaction. I would not hesitate to work with them again, and I highly recommend their services to anyone in need of electrical work."

"I hired Prime Sine Electric LLC for a complete new electrical service and wiring on our 1937 home when purchased. It was in need of a complete gut-job. Spence did an amazing job bringing it up to today's standards. I mean, totally amazing transformation. Spence was professional the entire time through the quote process, customer service and final completion. He listened to our needs and gave input and helped us with planning the electrical needs of this old house. We can't recommend Spence enough and would hire him again in an instant."

"The problem turned out to be a burned out small electric door switch. I believe the price was way too expensive for the service performed and the price of the door switch. What more can I say? It got done."

Electrical questions, answered by experts

A bigger breaker alone probably won’t fix your problem of frequent tripping. But if you upgrade an electrical circuit to a higher amp rating, or upgrade your breaker box to handle more amps, it could solve your tripping problems. Consult a qualified electrician about the best course of action.

If the electrical wires you’re working with are too short, one of the easiest ways to elongate it is to extend them with a push-in connector. These user-friendly tools help you splice two wires together with little fuss or the need for extra tools, like a crimping tool, which is an older way of extending wires. As long as you can stripe the ends of a wire, using a push-in connector shouldn’t be an issue.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

Unless you’re a licensed electrician, you should not DIY any electrical work in your home. Working with wires and electricity is potentially dangerous to both you and the structure you’re working on, and it could lead to house fires or electric shock if you’re not 100% sure what you’re doing. There’s a big difference between changing a light switch cover and rewiring an entire home. If you’re staring down a potentially difficult electrical job, give a pro a call.

A ceiling light will usually have two or three wires: black, white, and sometimes green. Black wires are positive, or hot, while white wires are negative, or neutral. The green wire is the grounding wire. 

When you’re wiring the light, connect black to black, white to white, and green to the grounding screw.
