i am in an old house with 50a dryer outlet on a 40a circuit breaker. The new dryer comes with standard 30a manufacturer recommendation. I did have an existing 50a pigtail wire i am planning to hookup. However i wonder how risk it is to do so. Any advise will help. Thanks

A dryer should be *separately* fuse with usually dual 30 amp fuses/breakers (check the installation instructions). NOTHING else should be on the dryer's circuit nor should its circuit be over fused at the box.

The rating of the outlet itself just means it can not be used in a situation where that amperage is exceeded. Its rating has nothing to do with how big the fuses/breakers should be for the dryer.

If you're not sure what you're doing, I suggest you call in a professional.

dryer is on a seperate circuit (dual 40A). Nothing else is on that circuit. However, the old outlet is for 50A output. The pigtail wire is bigger than currently used 30a. The new 30a cable can only be plugged into 3 hole wire outlet with the top one as "L" shaped. I have three "I" shaped outlet.

Either i have to call electrictian to change the breaker to 30a, change the outlet to this "L" shaped, and then plug in the new system, Or, I just use the old cable (50a)to plug into the old outlet.

However, my qestion is whether this 50a cable will overheat the dryer and become a fire hazard.

** I have three "I" shaped outlet. **

It sounds like you have a stove outlet installed. It should be changed to a proper dryer outlet.

** my question is whether this 50a cable will overheat the dryer and become a fire hazard. **

No. A 50 amp cable/outlet will handle 50 amps of power. Since a dryer should only draw 30 amps (at most), that is less than the maximum the 50 amp will handle so it would not be damaged nor would using it cause any damage.

** Either i have to call electrician to change the breaker to 30a, change the outlet to this "L" shaped, and then plug in the new system, Or, I just use the old cable (50a)to plug into the old outlet. **

You should be having the breaker changed *regardless* of which cable you use. Over fusing a circuit defeats the purpose of the fuse/breaker to begin with. Check what size of fuse is recommended for the dryer and get that size installed, NO bigger!

But you should still change the outlet to a proper one for a dryer to avoid confusion.
