Electrical questions, answered by experts

Whether you need electrical upgrades depends on the electronics your game room includes. If your game room will have high-powered electronics, arcade machines, or a home theater, you may need to upgrade your electrical panel or add dedicated circuits. An electrician can assess your current system and provide an estimate for any necessary upgrades.

Yes, the National Electric Code (NEC) requires at least one GFCI outlet in each sectioned-off portion of an unfinished basement, partly to ensure a power source is available for a sump pump in case of flooding. If you install multiple outlets in your unfinished basement, all of them must be GFCI-protected. For finished basements, standard outlets are generally permitted, but at least one GFCI outlet is still required per circuit. Keep in mind that local municipalities may have additional codes, so it's best to consult a licensed electrician to ensure your home is fully compliant.

Outlets do wear out, usually within 15-25 years, but they can fail even sooner than that —sometimes in a matter of years. If your plugs always slide out after you put them in, this is a sign your outlets need to be replaced. Additionally, if your outlets are damaged, cracked, discolored, or regularly tripping the circuit breaker, they may be at the end of their life.

Yes, professional installations typically include wiring, switches, and circuit adjustments for safe operation.

Unless you’re a licensed electrician, you should not DIY any electrical work in your home. Working with wires and electricity is potentially dangerous to both you and the structure you’re working on, and it could lead to house fires or electric shock if you’re not 100% sure what you’re doing. There’s a big difference between changing a light switch cover and rewiring an entire home. If you’re staring down a potentially difficult electrical job, give a pro a call.
