Capacity Of An Armoured Cable.

Depends on why he did it, and which way you look at it (as in earth in with neutral or neutral in with earth). Power stations are not bound by BS7671 anyway so moot point.

plenty stuff is done differently. he may have seen something done there that he assumes can be done in his house. same as some people who see DNO using straight con then assume they can use the 'offcut' to run to their shed
