Hi everyone,
I have a question I was hoping a member could help me with. I recently acquired a Performax Supermax 25×2 sander for free. I’ve had to put some $$$ into it as it was not stored well and some things have rust and pits. Anyway… my question is regarding the electrical connection. I live in MN and I’ve contacted the new Supermax tools company for parts and electrical info. I’m told I need a 30amp circuit. I was also told I need a 4 prong plug, 2 hot, 1 neutral, 1 ground. All of this makes sense. Except for my machine has a 20 amp 240v plug with only 3 prongs. I know the plug was replaced by someone else as there is a price tag on it. The electrical cord going into the main control box is 12/2 (2 hots and one ground). For a 30 amp circuit I thought the cord should be 10 gauge??? On the circuit board there are only 2 connections and a ground. I have a feeling on the older designs they used only 3 wires instead of 4. Here’s what I’m hoping someone can help me with. If anyone has this sander would you be able to post a picture of the correct plug and cord gauge for me? I always thought 10 gauge was for 30 amp and 12 was for 20 amp. I don’t want to put a 30amp plug on the machine when it was meant for 20amps.
Thanks for all of the help everyone,
I really appreciate it.
Eric
