Ground wire to metal box

I am using metal handy boxes for receptacles. 3232TRWR Pass & Seymour receptacles and metal covers. Do I need a separate ground wire for the box or will it be grounded with the receptacle?

Not a separate grounding wire, just use a green grounding screw in the back of the box and loop your grounding wire around it before going to the receptacle. Self grounding receptacles are fine, but don't take into consideration someone later changing the receptacle to a non-grounding one.

Is this receptacle self grounding? I don't want to use a screw to the box.

Why not. If it is an interference issue then use a grounding clip.
Is this receptacle self grounding?
The purpose of the self grounding receptacle is to not have to put a ground wire on the receptacle. It is not to use the receptacle to ground the box. If you use the receptacle to ground the box then you loose grounding if the receptacle is removed. You are creating a safety issue. The ground wire must go to the box if it is metal. There is no exception.

3232TRWR are tamper resistant and weather resistant devices, they are not self grounding. For self grounding you need 3232TRSI for tamper resistant self grounding, or 3232SI for standard self grounding. I am not sure why you are using weather resistant devices.

I would also recommend not using handy boxed. The get overfilled too easy. I recommend using 4"x4" steel boxed with mud rings.

Do not use handy boxes. They are too small for more than one cable and device. Use 1900 boxes with covers.

You MUST ground the box. You do not need to ground the device if it's self grounding, or it's in a surface mounted box with the plastic washers removed.

One small note: The "I" in 3232SI indicates the color of the device. I = Ivory, W = White, LA= Light Almond. So a white standard self grounding receptacle would be 3232SW.
