SOLD FS 3hp single phase Unisaw w/pre Delta Biesemeyer

[Howie]

Reason for selling: I have another 3 phase Unisaw (3 phase) I am putting into service.
Located 15 mins south of Raleigh. Non-commercially Unisaw used in VG condition, currently under power and can demo/tryout. The Biesemeyer was NOS when I mounted 2 years ago. It is commercial version.
Reason for selling: I have another 3 phase Unisaw (3 phase) I am putting into service.
It is a 220 saw but I am running on 2 seperate circuit 110 outlets. Easy to switch back to single 220 cord.
Has front and side extenion to cut 4x8 sheets solo. $2200.

Maybe good that you are selling it.

Running it on two circuits can be very dangerous. Tripping one breaker or fuse leaves power on the saw. It may not run this way, but it's dangerous. In the event of a fault or short circuit, both lines need to shut off. That's why they make 2 pole circuit breakers with their handles tied together for our 240 volt single phase power. Either one overloading turns off both.

In the USA we have 240 volt Delta connected 3 phase or 208 Wye connected 3 phase with Neutral. We do not have 220 volt nominal 3 phase power.

Our single phase home power is center grounded single phase and 240 volt nominal, so 120 volts from either line to Neutral, which is grounded at the main service entrance. Even with 2 hot wires, it is still single phase.

I would have noticed a leg dropping out and never tripped either of the circuit breakers. No electrical smell ever or other signs of heat around switch/motor or panel. I agree not ideal but the lady of the house wanted her new kitchen cabinets built. I just put in a subpanel and would be glad to demo the saw of either set up for as long as someone would like. I would hope your comment would not place doubt in the condition of this saw. Like I wrote in the post I would be keeping it but the 3 phase unit I bought has a longer Biesemeyer.
