Electrical FAQs, answered by experts

The size of your home will help determine the size of your electrical panel. Usually, the decision comes down to a 100-amp electrical panel versus a 200-amp panel. Smaller homes, especially those without an HVAC system, may be able to get by with a 100-amp panel. 

If you have a larger home or need to power AC, a 200-amp panel should be the best fit. It’s unlikely that you’ll need a larger panel than that unless you have a larger home or unique electrical needs, but an electrician can help you make the final call.

If you’re interested in exploring other avenues to completely upgrade your electrical panel, it’s also possible to add a sub-panel, which is a smaller panel that connects to what you currently have in place. This way, you can add additional circuits without having to swap out your main panel.

Old electrical systems may have more problems than newer ones. In some cases, like if your home has aluminum wiring, it may be necessary to update your electrical system. You should also update your home’s wiring if it still has knob and tube wiring, which is considered dangerous by modern building standards. If that applies to you, get in touch with an electrical professional near you to obtain a quote.

Incorrectly wiring a single-pole switch results in the connected light or device not turning on or tripping the circuit breaker. Although it doesn't matter which terminal the hot wire and the load wire connect to, mixing up a circuit wire with a ground or having loose connections can prevent the switch from working. 

In the United States, home outlets support a standard 15 amps, but you can upgrade per outlet if necessary. Most single-family residential homes have a maximum overall amp rating, usually 100 to 200 amps. Very old houses may have less than 100 amps, but that’s rare. Large homes often come with amp services above 200 amps to support modern lifestyles.
