"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

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.

The most likely cause of accidentally flashing lights is that a regular bulb has been replaced with a flash bulb by accident. If that’s not the case, you should look for a bulb on the strand that is not quite seated properly and will lose its connection when it’s touched or moved.

You shouldn’t try to touch the electric fence, as it will shock you. Typically, the shock is low enough to be uncomfortable to humans or animals that come into contact with the fence. But an electric fence with high voltage, or a faulty fence, could shock you and cause serious injuries when touched.

Well pumps need power to run, so they can’t function without electricity. If your power shuts off, there can sometimes be enough pressure in the water tank to allow for a lucky flush or a bit of tap water—but this won’t last long. It’s a good idea to have a backup generator or an alternative power source like solar if you’re worried about losing power.

Yes, a whole-house surge protector needs a designated breaker in your electrical panel. You will need to choose a double pole breaker that has two wire terminals so that your surge protector can connect to the breaker. This breaker needs two breaker slots inside of your panel. If you do not have room, then you will either need to adjust some of the existing breakers in the panel box or hire an electrician to install a subpanel.
