Measuring electricity use

Kill A Watt meter?
This should get the results you want. I'm not sure how many amps it will handle.

I'm not sure what you are asking about either...

This is what we do when hooking up to the house/garage 15AMP receptacle

Before hooking up to the Garage 120VAC receptacle I would use a circuit tester from LOWES -WALMART that looks like this


Do not use the garage 120VAC receptacle if it does not check out "CORRECT" by the correct position of the tester lights...

What I do is use two 10-GAUGE (10-3) HD Contractor type 50-foot that run out towards both trailers. I have used a 12-gauge (12-3) long extension cord with out any issues but would never use the 14-16 gauge "RED ORANGE" smaller size extension cords you find at LOWES-WALMART. They are just too small to handle the trailers.


Out in the middle of the yard I use a RV30A-15A DOGBONE STYLE long adapter plugged into the 50-foot extension cords. These come from WALMART and look similar to this...


I could never use the small round black type RV30A-15A adapters as they always tend to get hot me when used just a short time...


What you don't want to happen is for the adapters to heat up your shore power cable which might end up looking like this and will need to be replaced.


Now all I do is plug the 30AMP trailer SHORE POWER CABLE into this RV30A-15A long adapter laying in the middle of the yard.

To insure the 120VAC power source is safe to use I will use one of these RV PLUG IN 120VAC AC voltmeters (AMAZON) plugged into a receptacle inside the trailer that is in a good view spot so you can glance at it when you need to. This will check the 120VAC level coming from the house. The part I like about this meter is it has a safe zone "GREEN" printed on the face and if the AC voltage is within this safe limit then is ok to use the power - even for one roof mounted air conditioner unit.


I will turn a few thing on inside the trailer for 10-minutes or so and then back outside and check all of the connection points to see they are not getting warm to touch. This includes the garage 120VAC receptacle.

We use the extension cord and RV30A-15A long adapter when on the road alot. You never know when we may need some power sometimes. Works great when visiting family - I just hookup outside their house and we sleep in the trailer.

Hope this helps

I have a load meter on my distribution panel that shows how many Amps I am pulling.

Do you mean 30 or 50 amp external electrical receptacle on the outside of someone's home that you would be attaching a stadard RV 30 or 50 amp cable from your RV to that receptacle?
