"Second time using B-Tec electric and I think now they are my go to electrician. I used them previously to upgrade my panel to 200 Amp and this time to hook up my new electric water heater. Both tasks were completed perfectly and fairly priced. I highly recommend B-Tec electric!"

"The RYB team delivered an excellent job for a fair price putting in a new circuit. upgrading the panel and wiring a heat-pump installation for me. They were neat, honest and respectful; answered my questions, explained what they were doing and why. They arrived when they said they would, worked hard all day in my nasty basement. And the Electrical Final Inspection... 5 Stars. Thanks"

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.

A voltmeter measures the voltage of AC or DC electrical current. Unlike a multimeter, measuring voltage is a voltmeter’s only function. Voltage is the potential difference between two points within a circuit. Measuring voltage with a voltmeter can help identify wiring issues or determine whether a battery is dead.

While the National Electrical Code (NEC) does not set a strict limit, a common guideline is to have a maximum of eight outlets or receptacles on a 15-amp circuit. This rule of thumb, which equates to about one outlet per 1.5 amps, helps keep the total electrical load safely below 80% of the circuit breaker's capacity. It is important to consider the power demands of any devices or appliances that will be plugged in, as overloading a circuit can lead to tripped breakers or create a fire hazard. To ensure the safety and code compliance of your electrical system, consult with a licensed electrician.

If the electrical wires you’re working with are too short, one of the easiest ways to elongate it is to extend them with a push-in connector. These user-friendly tools help you splice two wires together with little fuss or the need for extra tools, like a crimping tool, which is an older way of extending wires. As long as you can stripe the ends of a wire, using a push-in connector shouldn’t be an issue.

Electrical meter risers connect your home’s electrical meter to overhead power lines so you can receive electrical service from the grid. Electrical meters also have a weatherhead, which protects the utility lines connected to your home’s electrical system via the service entrance cable. Risers connect the weatherhead to your electrical meter socket, which connects to the meter.
