RV Electrical Safety: Part X – GFCI Testing

RV Electrical Safety: Part X – GFCI Testing

A perfectly isolated electrical appliance should have exactly the same amount of electrical current going out and coming back in. For example, if an applicance draws 7.000 amperes of current from the black/hot wire, then exactly 7.000 amperes of return current should be coming back in the white wire. However, if there’s any secondary connection to the earth/ground from something like our happy camper poking a piece of metal in a socket while standing on the ground, there will now be more current going out the black wire than is returning from the white wire.

RV Electrical Safety Part IX – In Review

Oct 12th, 2010 | By

I’m using this week’s column in a two-fold manner: 1) As a review of where we are in this 12-part series on RV electrical safety; and 2) As a call to action.

We’ve now completed Part VIII of this series, and have only four more RV safety articles scheduled. (See below for what’s been covered so far.) Part IX will be on GFCI troubleshooting; Part X on extension cord rewiring; and Part XII will be on basic CPR techniques — in the event of an electrocution. (I haven’t decided what Part XI will be just yet, but perhaps it will touch on electrical safety around boat docks since many of you also enjoy boating.)
