some clarification on original post...
all dim ckts. were 2 wire stage pin and changed to 3 wire stage pin - except 1st electric
1st electric has 7 ea edison 2 wire individual wire mold plug strips running the length of the pipe with an outlet every 24 inches on each strip
a 2 wire adapter...
I volunteer in a small community theater that has a bank of 2 wire edison plug strips mounted above/ on 1st electric ( 7 ckts. total if I remember correctly) pipe is less than 30 ft
would it be better (less expensive ) to install 2 -3 stage pin plug strips across the pipe or install 2-3...
