Went to do an EICR this morning and was presented with this.
Obviously at one time the lighting cable was in one of the consumer unit ways with a five amp fuse but when they installed the shower they had no spare ways.So they just moved it over onto the socket fuse,left the 1.0mm lighting cable in and took it to a fused spur.
I am going back on Friday to fit a new metal clad RCBO consumer unit with enough spare ways.
