Have you heard this about machine power?
My 15-91 old power cord assembly bit the dust. So I got a new power cord and controller foot wire and they wired it into the original control foot at the sewing machine shop (milwaukee sewing machine Inc). Anyway a friend who works with lots of mechanical equipment, machines etc told me that those old machines use a ton of power. More than a car starter/charger. I didn't know that. Or is he wrong? However I am happy to have a grounded plug and newer power cord/ wiring to the control foot. Makes me a little less nervous. I had everything checked when I first got the machine and was ok. Then we moved things around and the power cord did not look so healthy any more so I took it in. (After popping a circuit even though it was plugged into a surge protector- though with the old Un - grounded plug that may not have even mattered. )
Anyway- do these old machines really use so much power they could fry modern house wiring?
