"My husband and I highly recommend Jeremy. We had power issues and Jeremy walked us through everything that was going on. He went over the pricing and stuck to it. He is quick to respond to communication. We are very happy with the work he and Austin did to correct and upgrade our electric service. We will definitely be using him for future electricity needs and recommend him highly!"

Electrical questions, answered by experts

You can check if an electrician is licensed in California by using the online check a license tool offered by the Department of Consumer Affairs Contractors State License Board. You have the option of searching by the license number, the electrical contractor’s name, or the name of the business to determine the electrician’s status.

Most upgrades take 1-5 days, depending on building size and wiring complexity.

At a minimum, you need an electrician to inspect the house wiring after a fire. The electrician will need to replace damaged or melted wires. If the electrical wiring is old, about 25 years or more, you should rewire the house after a fire. Old wiring can increase the risk of another fire, so replacing the wires is the safest option.

How many string lights can be on one outlet depends on a number of varying factors, including the total wattage of your circuit, the type of lights, the energy needs of the lights, and cord specifications. It’s better to play it safe here to protect your circuit, so figure out the max wattage of your circuit, compare that to the lights, and move on from there. Generally speaking, LED string lights require less energy than incandescent bulbs, translating to a higher number of lights per circuit. 

Be careful not to drop your voltmeter or multimeter. Even a small fall can affect the tool’s ability to measure with accuracy. Always store your tools in their cases in a cool, dark place. Also, avoid touching the probes to each other while they’re connected to a circuit or another electrical component, and never tamper with anything inside the device.
