So how do you guys determine the size of existing tails and sub main conductors when carrying out EICR or surveys.
The reason I ask is, today I have been looking through some EICR and the conductor size stated of some of tails and sub mains is different to what I thought just by having a quick glance.
I know experience takes a big part but insulation on the conductors can vary from manufacturers.
Has anyone used insulated calipers? Can you even get them?
