"John Valero and his partner did an EXCELLENT job. John was professional to work with from the beginning of the project through completion. He was extremely reliable (always showed up on time) and worked with my timeline. I would highly recommend Cawiamca Electrical and John to anyone needed electrical work."

"He's been the best electrician I've ever dealt with. I was extremely impressed and shocked. not only did he do a phenomenal job, but it's immaculate. There is not a little bit of wire sitting standing anywhere. He cleaned up, he was lovely, he didn't talk much, but you know, he was very busy all day because our entire electrical panel had been blown out from that storm. This is the 1st time since July 4 that we have not been sitting in our house with the lights flashing on and off."

"After meeting Ron the owner, he educated me of the benefits of replacing my 25 year old oil furnace and central air unit with a very efficient HEAT PUMP/AC unit. A real no Brainer decision. All electric, energy star rated and no more fuel oil. After a very reasonable quote, with veterans discount, I said I'm in. Two of his Team showed up on a Wednesday around 8am and by Friday around Noon my AC was on. Friendly, professional, attention to detail. Would highly recommend Cawiamca for all Heating and AC projects. Great company."

Electrical questions, answered by experts

Yes, you can use a 3/0 AWG wire for a 200 amp service, but only if it is made of copper, as 3/0 copper wire has an allowable ampacity of 225 amps. If you are using aluminum or aluminum copper-clad wire, you need to use at least 4/0 AWG.

An estimate for electrical work should include an estimated number and an estimated price to complete the work. An electrical estimate should also include a description of the services to be provided as well as the materials to be used, such as wiring, switches, panels, or other items, and the cost for those materials. If any tax is charged, that should appear on the estimate, too. Some estimates may include additional options that can be added to the base price of the quoted job if the customer chooses to go ahead with the add-ons.

The NEC prohibits the installation of electrical panels within clothing closets. Closets are filled with flammable items like clothing, mothballs, shoe polish, plastic containers, and exposed light bulbs. If the panel develops a small electrical fire, it won’t take long to bloom into a real disaster. If you have an electrical panel in one of your home’s closets, move it as soon as possible with the help of a professional electrician.

GFCI stands for Ground Fault Circuit Interrupter, a standard safety addition to home power outlets. In rooms where moisture is more likely, like the bathroom and kitchen, GFCI outlets stop the current when certain kinds of shorts are detected, preventing shocks. Both GFCI and the similar AFCI (Arc Fault Circuit Interrupter) outlets are polarized and have clear indicators on the receptacle where hot wiring should go.

You shouldn’t hook up a solar panel directly to a battery. That can damage the solar battery and your appliances over time. Instead, install a charge controller between your solar panel and solar battery. Charge controllers regulate voltage, prevent overcharging, and minimize the amount of electrical current to protect your battery from voltage spikes.
