250v outlet


Hello members;

I have a 15a 250v duplex outlet. Instead of the typical 2 brass + 2 silver , 1 green terminals screws seen on a regular 120v recepticle it has 4 brass terminal screws ( 2 on each side) and 1 green screw.

Since this this 15/250v outlet is wired with 12/3 wire how is this wired?

Regular 120v recepticle when there is 1 hot it goes to brass, neutral(white) to silver and copper to green terminals.

250v recepticle has 2 hots, 1 neutral and ground.


Thank-you for your help
BN

There should be a wiring diagram included with the device. I'd take a look at that first.

No wiring diagram. It's a hubbell p-2356 . Tried looking for one online but no luck.

From what I saw of this device is it is a 250V (only device). Which means it only has connections for the two hots and the ground. If what you are plugging into this device requires a neutral, this device will not work.

If the load does not require a neutral, this device is like a standard 120V receptacle. One phase to each side of the device, and ground to the green (ground) screw.

So would I just cap off the neutral if the device does not require a neutral?

So 1 hot to upper brass screw and second hot to lower brass screw?

Woah hold on that one.,



Is that the one you are refering to this receptale ?

If so you can not use the upper and lower screw on the same side otherwise it will result a direct short circuit which that is very dangerous.

The correct way is take one hot conductor on one side ( brass screw ) and the other hot conductor on the other side of brass screw and green or bare conductor on green screw that it.

The red or black conductor it don't matter which way it will be as long one at each side of the receptale.

Merci,
Marc

I have been trying hard to simply answer the questions posed, but in this case, I have to ask what you plan on plugging into this receptacle?

Take a look at the literature that comes with the dust collector...

Quote:
Be sure the 240 volt plug is only used in an outlet having
the same configuration as the plug illustrated in Fig. C.
What you have and what is shown in the manual are not the same.

Both machines ?

I know I did read the PDF files which you left a link so the dust collecteur use the 15 amp 240 volt flat blades from factory.

So unless you are changing the plugs to the twistlockers is that right ?

Merci,
Marc

According to manufacturer specs, you are not allowed to do that and will void any warranty on the equipment.
