I was led to believe by a TD friend of mine that SJ is appropriate for areas where there will not be any traffic, ie... hanging on a baton, etc. If the wire is going to be on the ground with the possibility that somebody will step on it, then SO was what you needed. Please tell me he was correct, otherwise I'll have 2000' of SJ extensions that will be worthless (the SJ is 12-3).AVGuyAndy said:http://www.compcableusa.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=60123&Category_Code=
SOOW will work fine.
Anything "SJ" is not legal in this industry according to code. I don't think you'll have any problems though.
Making your own extensions is better, and cheaper in my experience.
Make sure you buy black cable. I beleive the link I posted is for black cable.
