Is a hi-power electric clothes dryer design still available?


I inherited a Kenmore "Sears Best" clothes dryer. It is more than 30 years old and works well. I measured the current recently at 25A. The plate lists 28A, 6,000 Watts! The dryer has never tripped a breaker.


Were electric clothes dryers designed to produce hotter temperatures 30+ years ago?


Is this current load too high for 2x #10 w/G on a 30A DP breaker?


Thanks, RogerDog

That is slightly more than the current dryers, but I would not be concerned of it being on a 30 amp circuit. As you stated, it is actually pulling only 25 amps. Your actual voltage is probably slghtly higher than the dryer nameplate stated resulting in lower amperage. When the voltage is higher, the amperage is lower while the wattage remains the same (watts divided by voltage equals amps).

Clothes dryer standard circuits are 30 amp. With those numbers the breaker should not be tripping.
Unless your dryer runs non stop for 3 hours continuous, it is a non-continuous load.

This is wrong for resistive elements including the dryer heating element.

The resistance is relatively fixed (varies a little based on temp), the current is determined by voltage and resistance.

Wattage is just a rating and varies in the real world as voltage changes.

Dryers can cycle the element to not overheat.

Most are 5000w when the element is on.

Its the least efficient appliance in the home.

It will be nice when the ultrasonic dryers hit the market.

^There are heatpump dryers out there.

I just use a indoor rack, no wasted energy.

is that reading for a double-pole 30amp 240v Dryer plug and breaker?
