110 shore wire

What gauge is shore wire.? Looks like 12-2 3 wire.
Possible to make one from Home Depot.Can I get the proper end for the As connection there?Or a specialty item.I need to go 75ft. any problem with this length?

It should be at least 10 gauge for a 30 amp circuit. You might have problems finding the correct ends at Home Depot. Try a camping or RV supply place. This is what you need for the male cord end: http://odmrv.com/catalog/index.php?main_page=product_info&cPath=78_113&prod ucts_id=1019

I know Camping World sells both the male and female ends, but their web site seems to be down right now.

75 feet at 10 gauge might be pushing it if you plan on running things like the a/c or an electric heater. Might want to go up to 8 gauge for that distance.

For 75 feet, a # 8 wire is a bare minimum, if you want to use the AC, etc.

You would be far safer to use # 6 wire, and then you could go to 100 feet.

It's always best to have a little reserve, than a little "not enough".

Cords are typically 10 Gauge and use a NEMA 30-TT plugs/ receptacles. Wire gauge needs to be considered when the length of cord run is determined. Longer runs require larger diameter wire in order to compensate for voltage drop over the run length.

I've seen the NEMA TT receptacles at Home Depot and Lowe's in some some of the larger markets.

Regards,

Kevin.

Home Depot sells the RV 30 amp plug just make sure it is the RV plug.

You can get by on 8/2 with ground but figure on a 2.5 to 3V drop when running AC and other stuff.
Normally not a problem until you hook up at a CG with 110V to 108V at the power post. Now you have a potential low voltage problem.

Best to be safe and go with the 6 gage.

Original wire may have been 10 gage but it was ony 20 to 30 ft.

As noted the gauge depends on the length of the run. But more important what is the gauge feeding the receptacle. Just up sizing the extension cord will not allow you to run the AC if the receptacle is fed by a smaller size.

Now if you are just parked and only running the battery charger # 12 will do.

You will need braided wire, not solid conductor. The solid wire is much too difficult to use. Braided wire is expensive and with the ends and making sure everything is waterproof (including the cable), it might just as economical to buy an already made cable, except all the ones I could find on the internet are 10 gauge for either a RV cable or an extension to attach to the RV cable that comes with the trailer. 50' extensions are readily available, but it will be questionable if you want to run high amperage appliances such as A/C, microwave and toaster. If you make your own, it should be at least 8 gauge and maybe 6. Voltage drop charts shows 75' for no more than 3% voltage drop would come between 6 and 8, but they don't make 7 gauge.

Just checked my 30 amp cable and it is 10-3 good for 30 amps when plugged directly, gets warm when using 15 amp adapter plug with one a/c running. AS wired so that only one a/c can be run off shorepower, but both can run off genset.
From what has been written so far I would be safe to have a 8-3 25 foot extension for using less than 30 amps.
Large rigs are wired for 50 amps each leg , but it is 220 so actually when comparing to mine it is equal to 100 amps.
