Arrow Replacing wall switches ....

Hi Guys,

I need your help ...

I am upgrading the regular toggle switches with the Leviton Single Pole Decora Wall Switch to control lights and fans through our home. Our home is less then a year old.

The regular toggle swtich which we have installed today has two brass terminal screws and a green grounding screw, but the Leviton switch has only two brass terminal screws and no green grounding screw.

What should I do here? The guy from home depot said we could install those new switches without using ground or attache the copper ground wire to the box itself. Can someone confirm or reject that claim?

Thanks in advance.

If the switches have no ground screw then they do not need to be directly grounded.

The ground wire in the box should already be attached to the box itself, if the box is metal.

Just install the switches.

Article 404.9 (B), 2002 Edition of the National Electrical Code states

Grounding, Snap switches, including dimmer and similar control switches, shall be effectively grounded and provide a means to ground metal faceplates, whether or not a metal faceplate is installed. Snap switches shall be considered effectively grounded if either of the following conditions is met.

(1) The switch is mounted with metal screws to a metal box or to a non-metallic box with integral means for grounding devices.

(2) An equipment grounding conductor or equipment bonding jumper is connected to an equipment grounding termination of the snap switch.

Return your switches and get ones with the ground screw.

2005 code- 404.9 B

Exception to "B". Your allset. Use a plastic plate.
Metal box, make sure It is grounded.

I wasn't even aware that ungrounded switches were made any more. Were the ones you bought covered with like an inch of dust?

Strange..I have Leviton lighted Decora (single pole) throughout my home. They all have grounding terminal.

Look carefully, I bet they are there.

Exception to (B) would not apply as there is a grounding means available.

They switches need to be exchanged for ones with the grounding terminal.
