I'm adding 2x20 Amp circuits to a main panel outside, but the main has 3 wire system. Also the main has 6 spaces for circuits, which allows me to add this circuits. The problem is the 3 wire system.
My question is, it's ok to run the circuits and bond the neutral and the ground in the main panel?
All the boxes are bonded, so I figure it out if the neutral gets severed then I have the ground to allow the current take that path. I'm not sure if it's ok to do it. Maybe I should bond the boxes to the iron from the foundation. Thanks in advance.
