"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."

"The Pros from CA Electrical group were top notch. They were real electricians and knew what they were talking about. They were my top Two and I ended up going with another electrician based on cost at the time. I’m sure given the chance they would have gotten to a better price as well."

"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"

"Robert did an excellent job installing LED ceiling lights in our family room. I couldn't be happier with the finished work. The installation was very neat and professional. I would not hesitate to call Robert again for any future work. I will be referring Robert to anyone that may need some electrical work."

"All kinds of electric work. We have an auto repair shop in a large warehouse building. Needed tons of rewiring and lighting installed. Dave was able to handle EVERYTHING. The place has super high ceilings - no problem. Old panels and wiring needed updating - no problem. Office, parts room, bathrooms etc.. no problem. Highly recommended!"

Electrical questions, answered by experts

For a 200-amp underground service, you need a minimum of #2/0 American Wire Gauge (AWG) copper or #4/0 AWG aluminum or copper-clad wire. Don’t forget that, at minimum, you’ll need to use a 1 1/2-inch schedule 40 or 80 PVC conduit to successfully run a 200-amp underground service.

If it’s called a USB outlet without any further designation, it likely refers to a USB-A port. These are the original USB connections and are commonly integrated within power outlets. In recent years, USB-A cables have slowly been usurped by faster and more reliable USB-C cables. USB-C connectors are small and ultra-thin with a reversible design, while USB-A connectors are slightly larger and bulkier.

The major difference between a GFCI breaker and an AFCI breaker is that a GFCI breaker protects against fatal shocks while an AFCI breaker prevent electrical fires. A GFCI breaker senses when the electrical current to ground is overloaded and trips to prevent major accidents or injuries. AFCI breakers trip when it detects dangerous electrical arcing.

Compared to amps, volts, and watts, ohms are a different kind of measurement, though also very common. Ohms show the resistance of materials like wiring: How much they impede the flow of electrons. The reason household wiring is usually copper or aluminum is that these materials are affordable and also have lower ohms, which means low resistance/high conductivity.

With AC wiring, which is the kind most likely you’ll find at home, the black wire is “hot,” and the white is “neutral.” The bare or green wire is considered the safety ground wire. If you encounter DC wiring, it’s relatively easy to tell positive or negative wires apart. red wires are used to indicate positive voltage and black wires indicate negative voltage.
