I went to look at a job, where some copper thieves stole the parking lot light control wires, from a church none the less. I discovered the ground wire pulled with the home run is bare copper, which I thought was against code in a raceway. Am I right? Or was this another myth I believed in? Also what do you think about split bolting the 3 control wires and heat shrinking them in each hand hole? $50 a pop for the resin kits seems kinda pricing, when split bolts/heat shrink work just fine.
H2o: No issue with the bare to my knowledge as Greg said.
Now, the split bolt issue. Do you mean 3 control conductors, or you have to put 3 into a split bolt? Most, if not all split bolts are only listed/labeled (your choice) for two (2) conductors. ie; run/tap. Your AHJ may have an issue with 3 conductors.
HotLine I was going to put all 3 control wires in the split bolt, NSI industries claim to have a listed split bolt for 3 copper wires. However I am leaning towards Ideals blue weatherproof wirenuts, they are rated for wet locations and my connections are in a hand hole, so might truly be the safest and cost effective way to reconnect lights. Need to secure hand holes from future thefts any thoughts on how to? Was thinking drilling and tapping, but that diamond plate is thick.
Not sure where I got it in my head "no bare in raceway" however I will double check my WAC(Washington Administrative Code)book, however if previous installer was signed off, must be fine.
Bare copper ground in a conduit is not a code issue spec issue perhaps but not a code issue.
As for the split bolts/resin question. That depends on the "engineer" of the project. If done right, split bolt/resin is definently bullet proof for a long tern installation. Way better then wire nuts given their location. If no rework or add to later is not in the cards, bullet proof is a definent plus if the customers are willing to pay for it.
