Can I hook up to the home wiring?

[TexasVine]

Can I hook up my Sport 22 to my home wiring if I employ a 30 amp breaker on the wiring? I am asuming the wiring is the standard 20 amp wiring used for residential building. the house was built three years ago. I do have a generater but I am wanting t hook up to the house once in awhile. I do understand that I need to change out the connection box to mate with my RV extension chord.
Thanks,
Mike

Yes; and if you don't plan on using any high amperage gear, such as the heat pump, you can get a 20A plug to 30A input converter and just run via weatherproof extension cord.

If you want to wire up a genuine 30A camper plug, make sure the electrician knows NOT to make it 220v as some may believe they need to do for that type of plug.

The normal house wiring uses 14 gauge for 20 amp service. If you run a line and install a 30 amp breaker in the central box and an RV 110 volt box on the outside of the house, I would recommend you use 10 gauge wire. Then, you can use your air conditioner at home. If you are not going to use your air conditioner, I would suggest you simply by a 30 amp RV to 20 amp dogbone adapter and plug into the normal outlet on the house.

Correction: #14 wire is rated at 15 amps. #12 wire is rated at 20 amps. #10 wire is rated at 30 amps.
Do not increase the circuit breaker size above the capacity of the wire or the receptacle. Most homes have 15amp receptacles. 20 amp receptacles have one slot that looks like a "T" lying sideways.

Understand that the gauges listed above are dependent upon the length of the run as well. My 30A RV circuit was approx 45 feet from the box, which (IIRC) was right on the cusp of requiring 8ga wire. So I went that route. I actually went with 6ga....but that was only because the store was out of 8ga.

This was my second 30A RV circuit, as I poured a pad on the far end of the house. My first one was on the drive and a shorter run. That curcuit is only about 20 feet and 10ga was used.

Thank you everyone for the responses. Not the answers I wanted to hear but the truth will keep me from making a mistake. I will now run the power off the barn instead where I have the correct wiring

As long as you do not run the A/C you can run off the house circuit. You can run the fridge,lights, tv and even a small fan. We do this when we are cooling down the fridge for a trip.

Our AC will run on the low setting but not high when plugged into a 15 amp 110 vac outlet.

If you ONLY want to run the cONVERTER, a 15 AMP circuit is sufficient.

If you want to use the AS as additional space, wire a 50 AMP circuit. That way you will be "prepared" for any "upgrades"...

Just to be on the safe side, when you are running your a/c on the low setting, feel the wire, and the 30/15amp adaptor and make sure they aren't getting hot.

Just sayin'

Be certain not to exceed the capacity of your main breaker box.

I recommend adding a subpanel adjacent to where you will be parking.

Also a good comment to follow above... Wire sub panel for 110 not 220.

If you are going to the trouble of adding a sub panel; go for 50 amps with two receptacles 30 and 50. You may wish to run two AC units if you get a larger rig - the additional cost is minimal.

Yep ... and the extention cord if using one.

[Inland RV Center, In]

We have used a "pocket reference book" published by Sequoia Publishing, for many years.

The following is a small wire chart, 1 page out of 864 pages that lists all kinds of charts, scales and you name it.

These numbers are the maximum total length, including the present city power cable, subtracting the 25 foot USA cable. These numbers are for a 3 wire flexible cable.

The 36 foot coach cable length has been subtracted, therefore the following is the maximum length of an extension cord, that can be added, using a maximum of a 2 percent voltage drop.

If you want to be super safe with the current draw, the minimum wire size that should then be used, is a #8 3 conductor wire. If more current is used higher than the below numbers, then a voltage drop greater than 2 percent will occur. When that happens, running the AC, as an example, could cause the breaker to blow, because when the voltage goes down, the current increases, which could ruin the compressor. As the chart shows, using a extension cord of #8 wire, not more than 35 feet long, is the best overall. That size would allow a 30 amp draw for a distance of 60 feet, a 35 foot extension cord and the 25 foot cable from the coach. It's a MUST that you also add the current draw from the Univolt, and anything else that you may turn on, plus the current draw from the AC

For 20 amps, #12 wire no extension
#10 wire 21 feet
# 8 wire 54 feet
# 6 wire 104 feet

For 25 amps, #10 wire 9 feet
# 8 wire 36 feet
# 6 wire 79 feet

For 30 amps, #10 wire 2 feet
# 8 wire 24 feet
# 6 wire 59 feet

We installed this spiffy Midwest box with a 30A breaker and plug. It's worked great. We kept on throwing the 20A breaker with the feeble extension cord.

Whatever the Amperage, AWG and length of the run, always check for voltage drop. NEVER let it go beyond 10%.

While under load.

Well, I don't get that. It doesn't consider the length of the #12 in the house. If that is within limits, a #12 extension cord could certainly be used to the #12 limit.

In a house built in the past 30 years or so outlets are 20 amp with #12 wire.
