Temporary power
« on: July 02, 2019, 10:55:27 AM »
Trying to set up a temporary power pole off a utility box for a 30 amp rv. Do i need a 30 amp box specifically or could i purchase a 100 amp with 4 circuits and just add a 30 amp to the circuit? Im not sure if adding a 30 amp plugin to the 100 amp box is possible? Id like to power the rv on 1 circuit and a water pump on another circuit. Any help would be greatly appreciated.

You need a 30A/120v outlet to plug the RV into. It should be fed from a 30A breaker, which will be placed in whatever "box" (load center) the power comes from.  The box for the 30A outlet (aka receptacle)  would normally be separate from the load center box.

Something like this would do the job nicely.

Use 10 gauge (or larger) wire to achieve the 30A rating.

Here is a post about hooking up temporary power.

Two comments, First for 30 amp service you can go a little smaller on the wire size although the heavier gauge for 50 amp will work.

Second, the pictures are posted farther down the post so you do not need to click on Photo Bucket.

You can add a 30 amp breaker to a typical 100 amp temporary power pole used at construction sites, or a typical mobile home power pole, etc.

p.s. it should be noted that RV 30 amp outlets are 120V only, they are NOT wired 240V like similar looking old style 3 wire dryer outlets are.

Sure, I did it a few years ago.

 Just make sure your supply is big enough to feed both the 30 amp RV and what ever your water pump requirement is.

Option 1:  Meter-----30 amp RV outlet box with breaker

Option 2:  Meter----100 amp distribution center  30 amp SINGLE breaker----TT-30 outlet

Option 3 and 4 Same as one and 2 but "Meter" is followed by "Main Distribution panel" and the 100 amp distirbution center is changed to "100 amp sub panel".

In short either method works.. Just make sure if you go the 100 am route the supply line can take the load.

Check the minimum size service the utility company will connect. There might be a 100 amp minimum size.
