UK High Max Zs

[newfutile]

Most socket outlets should be on (RCD) Residual Current Device especially if they could be used outside, the maximum ZS for the lighting should be less than 1.84 ohms for a 13 amp bs1362 fuse,though a 3 or 5 amp may be better if loads permit

Thanks for the heads up. Please could you help unpack that some more for me or provide a reference for further reading.

The Rcd doesn't provide over current protection.
