 that will remove 26 AMPS from the timer block in my Charcoal '57 Frigidaire at spin up! The timer contact was rebuilt in the 1960's and"Mother-Superior" tells me that they used brass rivets which came loose, sure enough my contact is looser than a gooser and at spin up gets so hot you can't even touch the outer control tower. So I have put in a HONKIN huge power relay to take all the juice to the motor.
If you look around the world of electronics you will see there aren't many devices in the world that ever use 26 AMPS at one time! This is one of them.

26 amps?! Are you sure that amperage is correct? If so then you'd need a special circuit as normal 120v residential circuits are always 15 or 20 amps. Of course if there ever was a washer worthy of having its' own special circuit it would be a charcoal Control Tower thumper! | ||

They really do draw about 26 amps when they are coming up to spin speed. It's perfectly safe for a 15 or 20 amp circuit to draw that much amperage through it for SHORT periods of time (say while a motor is starting). Anyone who has watched one of these marvels start to spin knows that it throws that whole tub of water out in 15-20 seconds and is pretty much nearly up to spin speed shortly thereafter. That amount of time over-current is well within the parameters of a time-delay 15 or 20 amp fuse. I don't know the actual wattage of these machines once they are up to speed, but my guess would be that it quickly drops to the 400-500 watt range.

POWER RELAYS Well stated Mark [ Kenmore 71 ] your comments are right on the money. It is actually very easy to find relays this size if you look in a Grangers catalog for example rather than an electronics supplier, Jon I am glad you are getting this beautiful machine running for the upcoming appliance testing and trials . | ||

Thank you Mike I forgot about this video and Robert's rah-hah Frigidiare!!!
Yes it whomps up to 26 amps briefly then settles down to around 2-3 amps for a nice dry spin.
Last nite I tried using a jumper wire (green) you can see in the photo to supply the coil, but coming off the motor supply circuit there isn't enough voltage available to keep the contacts closed that motor sucks up so much power.. the low available voltage makes the relay chatter. I will have to direct connect the coil circuit independent of the motor supply circuit. | ||
