Is there any way to do a Zs read at the furthest point of a 6a mcb protected lighting radial without the mcb tripping? The circuit is not RCD protected. I can understand why the high current two lead test would trip it, but the non-trip three lead test also trips the mcb. Is this usual? Should I just add Ze to r1+r2 on every lighting circuit from now on?
Thanks.
Thanks.
