Why do power switch flip when dryer is on????

Everytime the dryer is on the power switch flips, even if it's the only thing on. Something it will flip if we have the a/c going in 2 or 3 rooms with the dishwasher or microwave it will flip. But it will ALWAYS go off with the dryer on. Any suggestion what to do?

and it's the outside switch!

Answers:
If it flips when you start the dryer, then you have a main problem.
If it flips after a while, it's due to the heating of the electrical wires.
You should need fuses with a higher Ampère level.

It's most likely inside ur dryer, if you can get into it with out too much trouble, look for [burnt wires or element] or maybe the motor is overheating.

more than likely it is a week breaker, usually a 50 amp, replace it.
call a licenced electrician
WARNING! most dryers I know of are 220 volts and should not be on with any other appliance! if yours is a 110v,, then you have an older house where the dryer is on the same line with other appliances and everything is drawing too much amperage.. run a seperate line for the dryer as it takes a lot to heat this thing up....you could have a fire if that breaker ever fails to "GO OFF"!
