Wiring a Male 20 Amp Plug?

Question

I just want to make sure I am doing this right.

I have just bought for $3 a 20 amp male plug. (I hope that is the right term). Its the part that will plug into the outlet. The plug has three prongs.
One prong is the U shaped one, which I assume is ground, and has a greenish screw on the inside.
One prong is flat and has a silver coloured screw on inside.
Last prong is also flat (but at right angles to the other flat prong) and has a brass coloured screw on the inside.

The wire coming into this plug has green, white and black.

So I assume that the green wire goes the green screw (U shaped prong). This is the ground?
I assume that white wire goes to the silver screw.
I assume the black wiire goes to the brass screw.

Does this sound ok?

The appliance is a small hot tub.
The plug it is going into is a GFI receptacle.

Answer 1

Yes and NO
First if the plug is wired that way then your right.
If someone wired the outlet wrong your wrong.
You never said if it was 120 or 220

120 your right still check the plug and make sure it's right
green to U
hot/black to brass
comm/white to silver

220 Green to U
either way but yours is the standard way.
Still check the outlet

Answer 4

You are on the right track but there is more to know; for starters 1) Black on the copper screw 2) White on the silver screw 3) green on the green screw ... NOW: You have purchased a 20 AMP male plug for a reason as apposed to a 15 AMP or the typical one with 2 verticle slots and one U slot (ground) The purpose of the horizontal slot on a 120 volt receptacle is to ensure that you have a 20 AMP receptacle to plug it into that matches it. The reason behind this is, if correctly done, the device you are plugging in with this new plug draws more power than your typical device, probably somewhere between 15-20 AMPS and it is most likely that you want this device plugged into a circuit all by itself or with little other "load" or devices running on it. That is why it is configured differently than a typical plug. Also you want to make sure the gage of the wire feeding the receptacle that you plug this new plug into is #12 gage and can handle the power of your device. If the receptacle is on a 20 AMP breaker you are most likely OK but not gaurenteed because sometimes people will purposely or not hook a #14 gage wire to a 20 AMP receptacle which is a NO-NO ... I know this is long but it truly answers your question and why your plug is a little different than normal ones! GOOD LUCK any questions e-mail [e-mail]! Most likely but not definitely if they gave you wires of black white and green you are dealing with 120 volts ... if they gave you black red and green or 2 colors and a green you are dealing with 240volts

Answer 5

If all is done by code,you should be fine.In my area,all GFCI receptacles are to be on a 20 amp breaker with 12 ga wire.And I think you are working with 120v because of the wire colors you describe.
But a good electrician will be able to confirm this if you are not sure.And the way you described your installation is correct.

Answer 6

I draw comfort that most of the answers concurred that your approach was correct.

I'd be very curious by your amended question... to know whether the receptacle is 220; I would infer that it most likely is 220. More yet, the new male plug is supplying electricity to what kind of appliance?

Answer 7

All is correct, except for the info on 120v/220v. If the tub is to be wired up 220v and not 120v then you are not going to be plugging in a male cord to a GFI receptacle. It will need a wire from the panel to the tub if 220v is required.
