I have modified the 10-3 14-50 extension cable to have one of the hot wires running out and back in the 14-50 receptacle.
This will allow me to use a clamp on AC meter near the PFC-50, keeping the AC current below the AC breaker. The 10 gauge wire can handle the 30 amps on an AVCON charging head. If you remember, at 30 AC amps into my PFC-50, I got 36.6 DC amps into my 132V pack (at 150V, 6kw AC use, 97% PF, on a 204VAC source). I also turned the current up on the PFC-50 to the 40 amp AC breaker limit, and got 44 DC amps into my pack. The 10 gauge wire in the 14-50 extension cable should not over heat if run under 40 amps continuously, and if the cord is not coiled up (it will get warm). It will be a couple of days before I can get a heavy gauge 14-50 extension cable made up to test at higher PFC-50 output currents properly off a higher amperage outlet. I might try connecting the PFC-50 to a 50 amp outlet and turn the output up to read the output. I would have to do this for only a short time as the 10 gauge wire can not handle that current. I would also like to read the voltage (power) loss when using the wrong gauge wiring. Now that Rich has made a charger that 'can' pump the power, we need to look at using the correct wiring to get all of the power to the pack. It will be interesting to see what amperage source I would need to get all 72 amps out of my PFC-50. On a 204 volt source at 30 amps I was pulling 6kw. But the difference between the AC current number and the DC current number was only about 5 apart. 30 AC amps : 36.6 DC amps 40 : 44 45 : 50 [That last number was run for only a short time. The 40 amp breaker did not pop as the electrician had a blower on the panel to keep it cool (he cheated).] So, I am going to guess that if I pull 50 AC amps, I will likely see about 55 DC amps into my pack. Does this mean I need a 80 amp source to get the 72 amps into my pack? But that will depend on the source. Its voltage, and wiring. Otmar has offered that I come over and suck some solar electrons. Since the weather is going to be cooler the next few days, less power will be needed for cooling Otmar's house (I am concerned I will max his house power, and pop his breakers). I will report when I test this out. :-zzz ===== ' ____ ~/__|o\__ '@----- @'---(= . http://geocities.com/brucedp . EV List Editor & RE newswires .
