An overloaded circuit can allow the wires inside your wall to heat up and start a fire. Most household circuits are rated at 15 amps, and if you exceed that significantly, the circuit breaker should trip. To calculate the load on a circuit, add up the amperage for all the devices connected, and be aware that inductive loads like motors can draw anywhere from 2 to 10 times the current for a brief moment at startup. Avoid using extension cords or outlet strips, and if you must, make sure they are rated appropriately for the devices connected to them.
