[RE-wrenches] MLSD module level shutdown

[Ray]

I totally agree; where else does the NEC allow loose single conductor 
cables to run unprotected? outdoors?  All because the module manus and 
industry in general has made no effort, zero, to accommodate any type of 
electrical industry standard K/Os for conduit, or TEK 90 (great stuff 
BTW).   If we hadn't gone this wacky direction, starting about 15 years 
ago, we probably wouldn't be having this conversation, because there 
would be much less reason for MLSD.

I could see whips of TEK 90 that plugged into polarized 2 pole quick 
connects mounted integrally to a J box on the back of each module.
