A Brief Overview of 50 Amp Generators

Before we get to know different 50 amp units, it’s important to understand more about Amp and how it related to watts.

When choosing a generator for your home, it’s always good to pick one that’s larger than your power requirements. A smaller unit won’t power most appliances in the event of an extended blackout. A smaller generator maybe fine only if you want to run the most crucial appliances. However, if you’re going to run major appliances, a generator capable of producing 50 amp is a recommended choice.

50 Amp Generators for RV

When choosing a genset for your RV, the essential factor to consider is how you’ll connect it to the RV. The most preferred method is through a power cord. It can be a 30amp or 50amp connection.

Therefore it’s always essential to ensure that the unit is compatible. Smaller RV’s use 30amp connection while larger models use 50Amp connection. For a 50amp RV, you’ll need a 50Amp generator.
