This was good, I am glad to find one installed in the actual condenser instead of the disconnect box. Yet, why didn't you shorten the wires? And, why didn't you pigtail the hots (not the ground which is permitted to double tap)?
why does it matter if installed in condensor or disconnect box? Wouldn't installing it in the box allow it to short out before the current got to the condensor?
How can this device shunt a surge to neutral without a neutral wire hooked up?
@@jimfrye4480 The ground will be bonded to neutral at the main pabel and will eventually find its way back. Besides, as long as is diverted and not absorbed by yhe unit is fine, it will find ground either on the copper rod or the transformer at the pole.
@jimfrye4480 the ground wire is used instead. btw it's a not a shunt, it's meant to take on the power surge directly and destroy itself hence the "sacrificial TMOVs" as he mentioned. Think of of it as a giant fuse meant to be blown and then thrown away after it has done its job.
It doesn't matter where it's installed especially when it's hooked up directly in line with L1/L2 whether at the contactor or at the disconnect electricity always takes the path to least resistance so it will ALWAYS hit the surge protector first.
Did you guys splice your units stranded aluminum wires with stranded copper wires?... You're not supposed to do that. Why not just make the unit with copper so you avoid the corrosion and code violation issue.
WHY DID YOU HOOK UP DIRECTLY AT COND? A 5 NANO SEC OFF REQUIRES MIN. OF 3' WIRE DISCONNECT BOX IS A SURE THING!
Can you please rephrase your question???
I dont see how that surge will even work like that. Its suppose to go in the disconnect box on the wire feeding from the main panel. The way you have it its going its going to hit the condenser and surge box at the same time. Think of it was a in-line fuse.
Electricity always takes the easier route, which is to the surge here. Poof!
