"I came home on a 90 degree day with half my bedroom having no electrical including AC. He called me right back. He went through and fixed the problem and explained everything along the way. The price was very reasonable. I would absolutely recommend him to anyone needing electrical work. Didn't push anything extra either. Great guy too!"

Electrical questions, answered by experts

The National Electrical Codebook indicates that there should be at least 6 inches of wiring in the breaker box for connecting purposes. When in doubt, err on the side more, because you can always cut some wire off but you can never add it back on, and if you don’t have enough you may struggle to finish wiring your breaker box properly.

Volts and watts aren’t directly convertible units—they measure different aspects of electricity. Volts measure electrical potential, while watts quantify the power. The relationship between the two is defined by the equation: Power (watts)= Voltage (volts) x Current (amperes). In other words, the product of volts and amps results in watts, but there is no fixed conversion of volts into watts.

The cost to upgrade an electrical panel ranges from $1,200 to $2,000, depending on the type of electrical panel you need and the size of your home. Amperage plays a central role in determining the cost, so calculate your home’s electrical load before purchasing. For example, a 100-amp and 400-amp panel vary widely in cost. 

To ensure batteries stop charging when they’re full, you’ll need to install a charge controller that determines when the battery is full. Once the battery is fully charged, the charge controller will stop the energy flow or divert the energy to the grid or other appliances. Without a charge controller, the battery may continue to charge, which can lead to less productivity and potential damage.

It is possible to change a light fixture by only flipping the light switch, but it’s better to be safe than sorry. Exercising extra caution when working with electricity is always important. Take the extra few minutes at your electrical box to cut the power at the circuit breaker. Once you’ve flipped the circuit breaker and the light switch, use a voltage tester to confirm the power has been turned off.
