30 Amp – Lessons in Electricity

Ampere – In practical terms, the ampere is a measure of the amount of electric charge passing a point in an electric circuit per unit time with 6.241 × 1018 electrons, or one coulomb per second constituting one ampere. – Wikipedia

As we planned our RV adventure we read that we needed to have plug adapters to step down our 50 amp RV to connect to 30 amp service. What that meant we really didn’t know but we have adapters to go from 50 amp…to 30 amp…to 20 amp (110v).

However….we’ve never been at a campground that only had 30 amp….until now.

From our readings we knew that during the summer you can only run a single A/C unit with a 30 amp connection and, since we have 2 air conditioners, we were aware of that limitation. So when we parked at this campground with a 30 amp service we didn’t know what to expect…especially since it is winter.

We now know that you cannot run the fireplace, microwave and clothes dryer at the same time. There are other combinations of things we cannot run simultaneously and we are learning what they are for now.

When the power goes out the 12V ceiling lights stay on but everything else goes out. We have to reset the circuit breaker outside on the power box then our onboard surge protector takes about 90 seconds to reset and the power comes back on.
