Can I run a 15/230v motor from a table saw on 15amp breaker in a garage?
It trips the breaker anytime I plug it in to any outlet in my garage.
If not, what should I do or how would I be able to do it?

Thanks

Well your garage outlets are not 230 (really 240) volts.
That saw motor is probably a 15 amp 120 volt motor which can be rewired to 7.5 amp 240 volts. Run a dedicated line using 12/2 wire and a double pole 15 amp breaker. Line can be hardwired to saw or you can use a 240V outlet and plug. You could also rewire saw to 120 V. Wiring diagram is probably inside the cover plate of wire connection to motor or at the switch.

No wiring diagram on motor or switch. All wires coming out of motor are black?
How would I determine which wires are which?
Thanks

Look closely on the motor wires. They may be fainty marked with designations such as T followed by a number.

Tel us every thing on the electrical nomenclature plate.

woodyGuy · Sep 3, 2009, 03:10 PM

Sure,
HP 1.5 SPL
VOLTS 15/230V
Hz 60
RPM 3450
Amps 15 0/7.5

That should cover it...

Thanks

Oh to answer Keepitsimple,

Motor wires:
(3) black wires - 1 - T2, 1 - T4, 1 - T8
Then
(3) more black wires - 1 -T3, 1 - T8, the last one
No # just lettering.

VOLTS 15/230V is a typo or worn off number. 115/230

Kiss,
You just answered my next question.

hkstroud · Sep 3, 2009, 03:24 PM

Woody, is there a little cover plate that covers where the wires go into the motor?
What brand and model is this saw?

woodyGuy · Sep 3, 2009, 03:28 PM

It's a box that encloses all the wires, including some kind of reset switch.
No diagrams anywhere.

woodyGuy · Sep 3, 2009, 03:43 PM

no, the motor has 2 holes where 3 of the wires come out into
this box enclosure (about 2X3X2 inches).

hkstroud · Sep 3, 2009, 04:22 PM

Motor make and model number?

You probably want dual voltage/thermal protection.

Depending on what you want to wire if for, you have to pick 115 or 230 or low or high nameplate voltage.

You also have to pick the shaft rotation. CW is when facing the shaft usually.

woodyGuy · Sep 7, 2009, 11:24 AM

Motor make is ROCKWELL.
Model No. is 62-042, it is made by Lesson Elect. Corporation

I think I would rather wire it for 115 V.

Thanks again

You don't have 7 wires labeled T2, T3, T4, T5 and T8 and P1 and P2?

As your facing the shaft of the motor, which direction do you want it to run. CW or CCW?

woodyGuy · Sep 7, 2009, 12:51 PM

Here is the config...

T2, T4, T8 & WH tied together.

T3, T5, & P2 tied together.

BL + BL Off SW. then P1 + WH Off SW

woodyGuy · Sep 7, 2009, 12:53 PM

The shaft needs to rotate CCW as your'e facing it because of the blade on table saw.

KISS · Sep 7, 2009, 04:46 PM

You seem to be wired for 120 V, clockwise, but motors are sometimes wired no-conventionlly.

So, for the moment the motor should run. Backwards usually won't cause the saw to lock up.

Let's see what happens, if you do the following.

Do this VERY CAREFULLY!

Start the motor spinning by hand (Use a push stick) and then apply power once the blade is moving. Don't care which way you cause it to spin by hand.

Does it run?

woodyGuy · Sep 7, 2009, 05:12 PM

I'm a little confused with your instructions.

The motor does run when powered up, so long as it's not attached to the belt, blade, etc. (and it rotates in a CCW direction and does not 'trip' the breaker at all).

I have plugged it several times w/out the belt or blade attached, so I know it works.
