Another electrical point. You could still have an overload on an extension cord that is rated for 8 amps but is plugged into a 15 amp recepticle. Remember the circuit breaker trips at 15 amps but you could have an awful lot of heat develop on an under-rated extension cord before the 15 amps is reached. The circuit breaker cant tell the difference between a normal load of say 10 amps and and a bunch of Christmas lights all daisy chained into this extension cord of 10 amps also.
