Generally I try and RCD everything...

    Advice about RCD's

    Just carried out a periodic on a childrens nursery (built 1994 not tested since), all tested ok but there are no RCD's. Extension leads laying about, radios being taken into the playground etc, what code if any? Be gentle with me it's Monday morning.
