Cam I have two GFCIs connected to one double gang box in my laundry room and if so can I do a single line connection so that they both can work independently?
I have a 12/2 going from the panel through conduit (copper wire) to the double gang box. I want to have each GFCI to run independently without using the load. Why, in case one shuts off the other isn't affected. the double gang box is standard. the device is a Leviton 20 amps. I was told that you can run 12/2 from the panel to the first GFCI black and white. Then connect the second GFCI using a jumper and attaching it to he second GFCI. Is this acceptable by code. we use a washer,dryer in the laundry and the garage heavy machinery. so why should this be a problem running two independent?

Take the incoming hot (black) and wirenut it to black pigtails going to the brass LINE HOT screws on each GFCI. Take the incoming neutral (white) and wirenut it to white pigtails going to the silver LINE NEUTRAL screws on each GFCI. Take all the grounds and wirenut them to each other and to bare pigtails to the green ground screws on each GFCI -- if you're in metal conduit with metal boxes, simply get self-grounding GFCIs instead.
With a single 12-2 and two yokes, you'll be nowhere near box fill for a double gang box, by the way.
