Power Cord

[Amber Gold]

My new H2O RO doesn't come with a power cord. What size and type of cord should I use? It'll be getting plugged into a 50amp rated plug. I want to size the cord for a 47 amp load in case I add a second tower in the future.

Thanks

I believe you would want a #6 stranded for 50 amp. Here is a chart that might help.

If under 25' run 8 ga stranded copper, over that run 6 ga stranded CU. You are best direct wiring it, but if you need to plug and unplug it, use an electric stove plug and recepticle.

Yeah...no wire. Surprised.

Thanks Dave. I have a stove type plug already set up and wired to the panel. The run is only ~10'. Do I need SOW cable or something different?

Home Depot and some Hardware stores have replacement cord for stoves in stock. Saves a lot of time and screwing around with the molded plug on the end. Next time you have to buy a new elec range chop off the power cord. I do that with anything large before it goes for scrap.

There are several you could use. If it is plug in, just be sure it is fine stranded wire (the individual wire strands are fine) and a flexible jacket. I like SJ but that's just me. The only issue with SJ is the sun eventually degrades the jacket, keep it out of the direct sun and you can get 20+ yrs, in the sun too much maybe half that. SOW will also work. Being after the plug you are not bound by code, but if you chose a solid wire or a heavy strand like THHN stranded you will get internal damage in time from flexing. Another choice is 8ga welder cable (or 4 lengths of single conductor). It is very flexable. If you go that route you can use 2 @ 8ga for the 2 hot leads (black and red) and then 2@ 10 ga for neutral and ground.
