50-30-120

Never done this and don't know if it is safe... My unit is 50 AMP... I have a reducer that takes it from 50 to 30 AMP... Then I have another that reduces from 30 AMP to 120... The plug I would use has a 30 AMP breaker in the house... Is this safe?

Thanks

Be very careful!! That you are asking indicates you are not real familiar with electricity. Unless that 30 amp outlet wired in your house was specifically installed for you trailer, most likely it is really a 240 volt outlet for a dryer or some other appliance. An outlet wired for your trailer will have one 120 volt pole, a neutral, and a ground in the proper positions. I would recommend testing the outlet with a voltmeter, or having someone who knows what they are doing, or an electrician.

You need an electrician. As they say don't try this at home.

I often use a 50 to 30amp reducer stubby cable then plug that into a 15 amp reducer and plug into a regular outside plug at our place. None of my regular outlets in my home have a 30 amp breaker and those 15 amp plugs are not meant to carry 30 amps.

The adapter I use is only rated for 15 amp and can only support the converter and some lights in the trailer and only used when we move the unit into place for packing up or unpacking.

rohrmann is correct you must be very careful you do not want to connect to a dryer, stove or other 220V outlet or unpleasant things will happen. Use a voltmeter or ask someone to check it for you.

If the plug you have has a 30 amp breaker and it's a standard (15 amp) plug, you already have problems! On the other hand, if the plug is a 30 amp plug, you may be able to use your 30 amp adapter. I'd need to see the wiring on the 30 amp circuit though.

I am guessing you mean the additional reducer reduces from 30 amp to 20 amp, or standard house outlet. The standard RV 30 amp is already 120 vac.

The problem I see is that standard house outlets are rated for either 15 or 20 amps. Makes me wonder if someone inappropriately (or inadvertently) installed a 30 amp breaker where it should be a 15 amp or 20 amp breaker. If so, not a safe combination.

If that 30 amp outlet is actually 220 vac then you definitely don't want to use it.

Be careful, Be very careful. A friend of mine thought he knew what he was doing and some how pluged his trailer in to a 30 amp plug he had in his garage, problem being it was a 220 volt dryer plug not a 120 amp RV plug.
Well it cost him $6,000.00 in damage to trailer and the appliances in it.

If you want to plug into a regular 115 volt 15 amp household outlet to power your RV lights and converter, you can use this: http://www.amazon.com/ParkPower-150S...o+50+amp+to+15

People have been known to do some really stupid things with electrical wiring.. The RV 50 amp and RV 30 amp plug will not plug into a dryer plug nor a welder plug they are a different configuration.

If you currently have a proper 50 amp to 30 amp RV pigtail reducer you can use this simple adapter to plug directly into your home 120V 15 amp outlets. I have used it with several older RV's I have owned and still use it with my 50 amp Montana. It is inexpensive and not meant for long term use but you can certainly run the converter for your lights and to keep the batteries charged.

I have the standard 50 to 30 to normal household style plug. I have used it at a county fairgrounds with a 20 amp circuit and even ran the air conditioner for awhile with the converter and other appliances off. It is now on a 15 amp circuit keeping the refrigerator going till we leave for Arizona.
