wire for 30 A

[dockmasterdave]

I am going to have a friend, who is an electrician wire me a 30 A receptacle for my TT. From the breaker box to the new recetacle will be @5 feet, then my TT 25' cord.
I just found some 10 AWG multi strand in two different colors. Is this going to be any good, or not?
Thanks for your help.

I'm with Tucson Jim... 10 AWG stranded is just fine. When I built my rv garage, I used #6 AWG stranded for 50amp service from my house CB panel to the sub CB panel in the garage. From there I ran #10 stranded up and over and down the other side of the garage (about 75') for the 30amp outlet that I use to keep the motor home batteries charged and to use items in the motor home when needed.

I had contacted the building inspector prior to using this wire (it also was some left over stuff I had stored) and he said it would pass code easily.

I've found that most states have pretty much the same building codes when it comes to the electrical. That said however, you should contact your local building inspector and get the correct answer from him/her.

Individual conductors are used in conduit. If you are going to run with out conduit then you could use 10/2 with ground Romex.
If using conduit whether it is rigid or flex you can run either stranded or solid, one white #10, one black #10 and one #12 green

I will certainly remind him about 120, not 240. Thx.

Be sure he knows this is to be a 120 volt circuit not a 240 volt circuit. 🙂

x2. Double check to make sure it's wired properly.

There is no prohibition in the National Electrical Code from using stranded wire of sufficient ampacity as long as it's copper. The code does require solid wire if it's aluminum. You are also prohibited from using stranded wire of any type in screwless terminals. You find these kind of terminals on the back of some switches and outlets where you can push the wire in instead of screwing it in.

Most people use solid wire because it's less expensive than stranded. In fact, stranded wire is sometimes used in conduit systems because it's easier to pull.

If you already have this wire and it's 10AWG, by all means use it for a 30A circuit.

2nd that on instructions to electrician that it is a 120 volt receptacle. They are used to wiring 220 volt 30 amp receptacles for water heaters, clothes dryers, washing machines, and such around homes. But a 120 volt 30 amp one for an RV is another matter entirely, very rare, and many people have found them wired for the common 220 volt in error.

I think, before I plugged in the trailer for the first time, that I'd take my voltmeter out and test it myself first. 'Course, I woulda wired it myself, too.

As noted above, make sure your friend understands it's a 120 volt, 30a "RV" receptacle, and NOT 220 VOLTS. It will have one 120v hot, one neutral, and one ground. Several reports on this forum of electricians assuming it's a 220v receptacle because it looks similar. 220 will fry a lot of expensive stuff.

Take heart - that 10 gauge wire can also be used in 12 volt applications that require 10-20 amps. You might still find a home for that wire. 🙂

Stranded #10 thhn wire is fine actually most would be better than solid wire. As for colors you'll need a white and a green or tape to make the wires white and green.

Agree, no stranded only solid conductor.

[time2roll]

Terminals may not be rated for stranded. No need to save 10 cents by using surplus wire. Have your friend bring the right stuff. Yes it is #10, 30 amp SINGLE breaker, 120 volts.

i hope your friend does not wire it 220 as others on here has had done by a electrician
