Hi - Crowdsourcing for help:

I live in a condo and my deeded ground floor space is wired to my electric panel in my unit on the 8th floor. The 240 outlet is wired to a 40 Amp circuit. My electrician connected a Gen 2 HPWC and I keep getting the Amperage decreased to 30 A and I get error messages:
“Charge rate reduced. Check for an extension cord or faulty wiring”. My personal electrician feels there is a nick or other issue with the wiring. The developer claims,

“
There is a 40 amp breaker with #8 wires used for this dedicated outlet. Furthermore we tested the outlet and lines with no evidence of a defect or damage to the lines. We also checked the voltage in the 8th floor electrical closet and found the same results as we did in the garage. Both tests showed no voltage drop or any damage to the wires. Therefore we determine there are no defects with this dedicated line.

i.e., the wires used have no nicks nor was there any voltage drop. After completing these tests, we determine there are no defects in the electrical line or connections. ”

please help! I’m on a time crunch for this!

i really appreciate it!
