Electrical questions, answered by experts

While tamper-resistant outlets are effective at protecting children from the dangerous electrical outlets, few things can be truly childproof. Children may still try to imitate their parents and adults by inserting a plug into the tamper-resistant outlet. Hiding outlets behind childproofing covers is not an effective solution to this, as those covers can be removed or even swallowed. Tamper-resistant outlets are the safest option to keep children safe in your home, but be sure to always keep a close eye on young children around any outlets or electrical devices.

Yes. Like other trained specialists, electricians need to be licensed in their state of operation, and carry specific kinds of insurance required by that state, which usually includes general liability insurance and surety bonds. When choosing an electrician, always pay attention to these details, and avoid electricians who can’t offer proof. When it comes to wiring, you want experienced, trained pros doing the work.

A correctly functioning outlet will not cause a fire risk if nothing is plugged in. However, if the circuit is overloaded or there is a fault with the outlet, the connecting wiring, or the circuit it is attached to, this can lead to the risk of fire or electrocution, even when nothing is plugged in. Turn off the circuit breaker immediately and seek professional assistance if you suspect a fault.

Your outlet should be a ground-fault circuit interrupter (GFCI). These outlets will cut power off in the case of an electrical fire, keeping your home and family safe. Extension cords can also be GFCIs. A local electrician can replace older outlets with GFCIs, if necessary.

Most 200-amp service breakers can support 40 to 42 slots for single-pole breakers or 20 double-pole breakers. However, you should not use all of the breakers at the same time. Avoid using more than 160 amps worth of power at any given time to avoid overloading your 200-amp system.
