changing to 240 volts

[Terry on P.E.I]

Just finished setting up my new 36-655 and I was wondering if it is a big job to switch it over to 240 volts. Does the motor have to be taken out of the saw to do this? I have tried it at 120 and the lights dim when I start the saw plus I have also heard having your motor hooked to 240 is better for it.Thanks in advance..Terry

Hi Terry

Look on the back inside of the motor cover, it will give you a wiring diagram for both 120V and 240V. You'll also need a 2 pole 15A breaker.

Terry,

Is your saw on it's own, properly sized, circuit? Sounds to me like that is more likely the issue.

I've read enough back and forth discussion over the past few years on the whole 120-vs-240 issue that I've come to agree with the people who maintain that it does not make a difference. It's the same motor after all.

There may be some minor advantage to changing to 240. I suspect though that most of the problem is related to cct size and distace from the panel. Voltage cvhanges in a motor anr usually accomplished by swapping some wire around in the small junction box on the motor itself, though I am not familiar with that saw in particular.

I have the Delta 36-655 and was originally considering wiring it for 240V. Instead put in a dedicated 20 amp 120V circuit with 12 gauge wire and you will be you will be surprised at the difference. A 15 amp circuit on 14 gauge wire will have too much voltage drop under load to efficiently run that saw, especially if there are lights or other devices on that same circuit. With the 20 amp circuit the saw will start up faster and has more power when the going gets tough. Wiring a 240v circuit will give the same benefit, but you will use up two slots in your breaker panel, will have to spend more money on the 240v receptacle, have to change the plug end to match on the saw cord, and have to switch the connections on your saw motor. Unless you have other machinery already running on 240, it's easier and less expensive to install a 20 amp 120v circuit.
