In-reply-to » The three orange cables plus a black cable, are the power wires running into conduit that leads to the house, 3 power lines and 1 24Volt lighting line. They seem to enter the box on the top right, which is cut to go around the 32mm conduit, is in fact a box to channel the extractor fan air to the outside of the power house. So I share the same hole with extractor fan and conduit for the 4 wires.

@prologic@twtxt.net Yeah it wasn’t. The housing shroud of the box to hold the fan has a 40mm half circle pipe cut into the box, that fits over the 32mm conduit space, so both fit through the 90 by 90 hole through the besser block wall. In summer, this fan will help keep the room cooler.
