Outlets and switches should be cool to the touch. If they’re not—and especially if they show scorch marks—you need to get a pro in for a look pronto.

Having to frequently reset your circuit breakers is another warning sign that your system is not up to snuff. And if you see even a tiny wisp of smoke coming from an outlet, an appliance, or from behind a baseboard, you should immediately switch off the main breaker and call for help.

If your lights dim when you turn on your microwave or AC, it may mean your wiring is carrying too big a load and needs to be upgraded. Also, watch for signs of damage from rodents—torn or flaked insulation and such. For some reason, mice and rats love to munch on electrical wiring.

Finally, make sure your breaker box is clearly marked, showing what circuits go where. That’ll make trouble-shooting a whole lot easier if the need arises.
