Taken from On Site Guide, Table 6D1 Method 3 (enclosed in conduit on a wall
in trunking etc.) 6mm 2 cables single phase, current capacity = 41 amps

Method 4 (enclosed in thermally insulating wall etc) 34 Amps

Method 1 (clipped) 47 Amps


I was reading from the same hymn sheet :-)


Most shower circuit's I've seen go straight up the wall across the loft and
down to the shower, so some where in between Method 3 and 4, and at most
going to be using 37 amps for max 30 min at a time.

But is it safe to make that assumption? Given that we don't know that
there isn't a 5m run of cable running through loft insulation, is it
safe to assume? I'm not being argumentative - I'm geniuinely curious
about the correct way of deciding this.
