Topic tags/keywords: tablesaw question

I’ve been scouring the internet and have not found anyone else trying to convert a Delta 34090a to 240v.

I’m just working out of my garage and most of the plugs are on a single circuit. Which makes running my table saw or any other tool hard to do if I’m also running dust collection (shop vac). I have already tripped the breaker once with just the table saw.

My garage already has a 240 outlet in it that gets no use so far. I’d like to change my table saw over to it rather than change that run over to 120 In case down the road i buy a bigger table saw or jointer/planner.

I’ll try to attach the pictures of the serial numbers for the saw and motor. Any help would be greatly appreciated.

Post a picture of the data plate on the motor, which will tell you if it’s dual voltage or not. I can’t find any info regarding a 34-090 saw… most likely it was a Canadian specific model number, but probably can be cross referenced to one of the US made versions.

Marathon Electric is now Regal Beloit in Wausau Wi. If you contact them with the numbers on the label they would be able to tell you if it is dual voltage. Hopefully the motor nameplate is still on it like mrUnix suggested. The phone number for Marathon Electric is 715-675-3311

Nope 120 volts single phase 13.5 amps. Run a new line on a 20 amp breaker and your good to go. Along with 12 guage wire.

Thanks for the info

I called into regal Beloit’s marathon technical number.

They were great to deal with on the phone but she had to go to the microfiche in order to try and find an answer. No luck as of yet, she gave me their engineering email address to try them.

Looks like mrg is probably right in this case.

Will update if the engineering company gets back to me.
