I understand your view and I agree depending on how you write the report.
If you go with something like this:
“Using a suretest xxx the circuits did not exhibit significant voltage drop”
This is not the same as saying the circuits are in fact reliable or safe.
Short of ripping the place apart no one can certify that the circuits are safe.
However it is certainly up to each HI to decide how far they go.
I am conservative, I would not want to do testing that may become destructive.
As I said I do not take VD in dwelling units to be a significant issue. I also do not believe it is fair to apply 5% VD limits on a electrical system after the job has been wired.
If you know for certain that the contract documents with the EC required less than 5% drop than IMO you should indeed look for it.
If it was a code minimum installation per contract upping the requirements after the job is done is not fair to the EC.
Maybe I would feel differently if the HIs report stated something like this.
“The electrical system appears to comply with local codes and is safe but some circuits exhibit excessive voltage drop”
Often the jobs I work on do indeed have VD limits per contract and as long as I know that going in I have no problem complying with them.
We have done jobs so large that 20 amp receptacle circuits required 4 AWG copper to stay under the 5% drop.:eek:
