portable battery pack to test caravan rcd's

aligarjon

Hi guys.   A friend of mine is setting up a business servicing caravans.  He is plugging into the mains to do some testing and his rcd tests are obviously taking out the house rcd.  I know there are battery packs available to keep the power on for electronic devices/routers etc if we have to turn the power off for customers working from home.  I don't have one myself.  Would these sort of things be suitable for testing an rcd on a portable caravan or any caravan for that matter ?

Thanks

Gary

    Cheers guys.   I will pass it on and let him do some  research.

    To be fair he did mention an isolating transformer.

    Well mentioning it is half the battle. Wiring it with a secondary side NE bond is the most important thing - then it is not really an isolating transformer in the normal (IT) sense more of  fault current breaker. But to test RCDs he would only need a few hundred watts as the duty cycle will be minimal - not need for some great arm stretching lump.

    Just using L and N is Ok, but do a supply polarity test 1st. Not all caravan leads preserve  LN sequence, and the idea of faking the CPC from the L instead of the N does not bear thinking about.
