Electrics

The Double Pole Power Points switch both the Active and Neutral Wires and prevents the neutral becoming ctive where the polarity is reversed somewhere, usually in a power lead or if the van or home where the active and neutral wires have been switched somewhere

If you are talking about double pole switching as apposed to the other single pole switching....then I believe its an electrical regulations issue.

When I did my camper trailer the electrician I consulted believes it is just a safety approach to ensure the trailer/camper is definately isolated when you beleive it is. Otherwise the power feed (active) could be still there and you have only switch off the nuetral. There are sooooo many parks and not all are modern and built where you can abolutley guarantee that the feed was wired correctly. So why not use double pole switching just to be safe.

Agree with above.
I think it's mainly to do with people who foolishly modify their extension cords and get the live and neutral wires reversed. The two circuit breakers ensure that power is completely removed from the caravan.

Its all about maybe saving someones life...maybe yours ????

Especially for people who are doing additions to vans themselves !!!

Bit like pulling apart an anderson plug ......you know that power is isolated !!

With 240V you rarely get an electrical shock...you usually get electrocuted !!!!

All my equipment in the van is double poled and in addition I use an Earth Leakage Protector ( those orange ones) when on caravan parks or in the bush using a generator

Woody, agree with theory,s above re double switching, but i dont think all the old vans had single pole.
Have been double polled as long as i can remember, except for those that have been upgraded buy home renovators i suspect.
