Distribution circuits in Section 705 location, RCD needed? Discussion ThreadDistribution circuits in Section 705 location, RCD needed? Electrical Advice
I just want to check how I should be interpreting section 705.
705.411.1 states required disconnection devices, the first two indents covering final circuits and sockets, requiring 30ma and 100ma RCD's depending on rating of socket.
Indent 3 says " all other circuits" need 300ma RCD.
Does that include distribution circuits, outside? Or is the word "final" implied?
The background - a fused down main supply circuit runs along the drive of an estate. About half way along the drive there is a main distribution cabinet. This used to be the drive side of the fence but has been moved to other side of fence, field of (usually) sheep.
It's in a massive IP rated double door enclosure. Several distribution circuits leave here going underground, with about 1 ft of SWA being accessible from ground to bottom of enclosure.
2 new circuits run to new hook up points within the same field. (This has created multiple issues with isolators and wiring systems being accessible to animals, and these will need to be resolved)
But the main question is whether an distribution circuit with the source and destination within a field with livestock needs to comply with 705.411.1 iii)
A secondary question is whether an underground distribution circuit with the source in a field with livestock and the destination elsewhere e.g. a house needs to comply with 705.411.1 iii)
It feels as though the intent of that reg is fire protection and aimed at indoor circuits but the wording is actually quite vague.
Getting the cabinet fenced off (carefully missing cables!) is of course an option.
