Oh give me a break you guys. Plumber are FAR worse with the "I am the only one on the job" mentality.
BTW HJ, YES, the center of a 4" stud IS the ONLY place to run the wire.
A) ANY electrician who uses a plumbing pipe to support his wires is a hack.
B) ANY electrician who uses someone else's drill holes in framing is a jerk.
3) ANY electrician who puts a panel right above pipes stubbed out of a slab is either a dumbass or was told to do so by the builder.
What about the plumber who runs a vent stack from a bath vanity sink right straight up from the sink, knowing full well that there will be a vanity light dead center over the sink?
It goes both ways guys, and out stuff is WAY more flexible that yours, remember that. You can push a wire out of your way, I cannot mount a pancake box right to your vent stack!
