How do I run a ground wire to a light switch?
I have the 'old' light switches that do not require a ground wire to work, all of the switches are connected to a control box on the attic. I want to install new switches, but all of the new switches require a ground to work? All of these switches are connected in series, the reason I know this, is because when one of the switches gets stuck, I can not turn off any of them, until I find the one is tick...
I want to run a ground wire to the new switch, but I can't because the metal box does not have a ground wire attach to it... |

Household switches do not need a ground to work, the ground only carries current in a short. Are you sure they are in series?. Perhaps they are 3 and 4 way? Unless they are closed completely they will not work. If you have only 2 wires, white and black, you don't have a ground in the system, common for old houses. If you are running a new wire, and the junction box is grounded, run a 14/2 from that point to the switch and pigtail a ground to the junction box ground.

how to run a ground wire when there is not an existing one...
How do I run a ground wire where there no existing ground, because the household light switches are old and they did not require one and I want to install new light switches and possibly a light dimmer too.
I know I could just ground from the metal box, but the box does not have ground because this is only attached to the 2 x 4 studs and no ground was ever runned to them... Is the easies way the attic? |

Merged several threads all related.
A standard switch does not need a ground to operate. A ground is used in current wring, as for several decades, for safety in the event of a short circuit, as explained by Ma0641. If you are located in the USA, just running a ground wire to devices with no ground is not allowed. If you could run a ground wire, then you can install new wiring with a ground in the cable. You probably get the impression the switch needs a ground wire because the new switch has a green screw on it, and the old does not. Again, the ground is not required for proper operation. |
