50a electrical plugs?
Voltage depends on the load.
With no load the voltage should be about the same as the house. Load it up to 45 amps or so, then take the reading, that is when it really counts. Bill 84 FC 35 SB "$quanderlodge" Terrace, B.C.

The easy way is to check the voltage in the coach. I have two 30-amp cords (end to end) to reach my coach. The voltage in the coach is within 1 volt of the voltage in the house (probably within the tolerance of my relatively cheap multi-meter) . You're probably just fine if you make the extension cord.

Its good to remember that if you are to hook an extention cord to a
pedistal or an outlet, the wire gauge to the outlet/pedistal from the E meter should take into account the length of the extention cord. I have a 50 amp pedistal that is 500 foot away from my main panel and 150 from a sub. I droped in a 240/30 amp breaker (60 amp total) to trip early and not overtax the long run.

Just because you are using a 50 amp plug, you dont need to mount a
50 amp fuse. --- In WanderlodgeForum@yahoogroups.com, "Gregory OConnor" > > Its good to remember that if you are to hook an extention cord to a > pedistal or an outlet, the wire gauge to the outlet/pedistal from > the E meter should take into account the length of the extention > cord.

50a electrical plugs?
Ryan,
I had to replace a missing 50 amp cord, and I found the original Hart-Arrow #7764 Hart-Lock connector, now Cooper Wiring Devices, 7764. I ordered it online at: http://www.electric-supplier.com/prod/co...324123.php or http://tinyurl.com/4g2g9h It was drop shipped directly from Cooper, and arrived within 2 weeks. Price is now $119.90 + shipping. Pricy, but it is the right one, metal, heavy, well made, and it fits. Looks like it will last forever.
