We all know, well maybe not!
So the basic rule of thumb is to make sure that every time you go to connect your rig, or unplug it, that the power is OFF!
Do not plug-in or unplug a rig that has a live power outlet, the chances of damage, arcing etc. can be bad for not only your RV, but it could harm you as well.
The other nice to have is a 110 volt polarity checker, (those little yellow things that you plug into a standard outlet and has 3 little lights on it) that tells you if the outlet is good or not. That little gadget can tell you at least if there may be a bad ground in the box you are connecting to, it won’t guarantee that the polarity is right everywhere, but it will at least give you a reassurance that the rest of the connection is probably good if the 110 circuit is good.
Next thing that is typically a DO Not Do, is to have the generator running at the same time you have shore power plugged in, or if you are switching between shore power and generator. The switching circuits that change from the shore power to generator can be damaged or burn up.
It is also a good idea to have a power surge protection device on your RV, if there wasn’t one built into your RV when you bought it, it is a good idea to buy an external one. These not so cheep devices can protect your rig from burning to the ground. The protect the RV in many different ways, 1 is from a bad power connection when you initially hook up at a park. Another is if there is a brown out condition, or for some reason the power becomes unstable or you lose 1/2 of the power connection your RV will be protected from damage because the unit will disconnect your RV. It will not power up your RV until the power is stable again. Well worth the $250.00 or more that you might pay for a good surge protector.
I will cover 12 volt, chassis and coach battery systems in a different post to be added soon.
Stay Safe and Camp ON!
