50amp to 30amp

[Billy O]

Newbe Question… will I harm my inverter if I’m useing 50 amp service with a 30 amp trailer?

Also can I hook my 30 amp surge protector to the dogbone hooked to 50 amps?

If you mean your converter (which changes 120-volt AC to 12-volts DC), no you will not harm it. It still will receive 120-volts just as if you were plugged into a 30-amp outlet. An inverter changes 12-volts DC to 120-volts AC for use by some appliances on battery power if the unit is equipped with an inverter.

Your 30-amp main breaker will provide overload protection to your unit's wiring from overcurrent situations.

Your surge protector will still provide protection to your downstream electronics when you have a dogbone allowing you to plug into 50-amp service.

Is it tecnacally a bottle neck when you use a 50a conection amd down it down with a 30a to connect to the rv.

It’s not a problem. We did that on several occasions with our previous TT when the 30 amp receptacle on the campground’s electrical box was not working.

If you are asking if it is a bottleneck, the answer is "no". When using a 50-amp to 30-amp dogbone you are feeding just one (of the two) 50-amp "hot" legs coming from the power post into the single "hot" leg of the unit's 30-amp connection. So technically you could have 50 amperes of current available up to the unit's main power panel, but the 30-amp rig's main breaker will only allow 30 amperes to flow into that unit. More than 30 and the unit's main breaker will "open" because of the overcurrent situation.

You actually don't have any more amp capacity than you have with 30a. Just from another source, The pedestal connections may not be as worn on the 50a.

A 50 amp outlet is capable of providing up to 50 amps. It doesn't mean that there is 50 amps going out all the time. The amount of amperage depends on what all you are running in your rig. One light may draw only 1 amp but the A/C can draw up to 20 amps. Your 30 amp main breaker will not allow a draw over 30 amps.


Did I say that right?
