"We were very lucky to find Emrom Electric and Emmanuel Mbisse. Our 100+ year old house in Berkeley needed complete rewiring after a short circuit and inspection. Emrom was able to start this huge job within a week or two, saving us a lot of money in tenants' dislocation expenses. Emmanuel was a pleasure to work with, providing explanations and giving us options along the way. He got the job done faster than we had hoped in a good, professional manner for a fair price. We would recommend Emrom to anyone and will definitely be contacting them for any future electrical work."

"Single Line Electric came to my house to view my need. 2 other companies I called wanted me to send a video of my home showing them my yard from the electrical box to my pool. They obviously didn't want the job. Nery came out and did a thorough assessment of my needs. His quote was reasonable and the project began soon after. I am very pleased with with Single Line Electric"

Electrical FAQs, answered by experts

Automatic gates don’t use too much electricity, and you should see a minimal effect on your utility bill. In fact, certain gate systems are entirely self-sufficient and rely on solar panels attached to or near the gate to power the motor. While a gate is large and there is a powerful motor moving it, it’s not something that sees constant use throughout the day. For most automatic gates, expect to see a utility bill increase of only around $10 per month.

Basic smart light switches are available for as little as $20. If you can install them yourself, it’s a home upgrade that won’t break the bank. Many homeowners view them as a worthwhile investment for the additional convenience and security they can offer. However, they are a little more tricky to install than standard light switches, so if you don’t have the electrical knowledge to do a DIY job, unless you need a lighting upgrade, remember these are a nice-to-have rather than a necessary purchase.

Yes, most electric heated bathroom floor systems require a dedicated GFCI-protected circuit to ensure safety and proper function. An electrician may need to upgrade your panel or run new wiring, which can increase installation costs. Always check local building codes and manufacturer recommendations before installation to ensure a safe and compliant setup.

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

The life expectancy of a circuit breaker is 30 to 40 years. However, how long your circuit breaker lasts depends on the condition of your electrical equipment, the amperage, your electrical consumption, and more. A breaker box that frequently trips from overload will last much shorter than a breaker box with the proper amperage for the number of devices and appliances in use. If your circuit breaker trips frequently, and you have also increased your electrical consumption, it may be worth upgrading your electrical panel to extend your electrical system’s lifespan—and save you the hassle of frequent power trips.
