Hello everyone,

A new small DB will be installed inside a garage for few lights and sockets. The feed will come from inside the house. Does it need to be an IP65 unit or can be the usual metal clad?

Thank you

Depends on if you think a metal clad is inappropriate for the environment. Either is fine.

Unless it is near a doorway where rain could get in (say 45 deg angle), or a known leaky roof, or where someone uses a sink/pressure washer, then I would not worry about meeting IP65.

But if it is only lights and a couple of sockets, and the house CU is already on RCD or RCBO supply, then why not just feed the sockets directly as a radial from a 20A supply and have a 3A FCU to switch the lights off that?

Unless the garage is not part of the domestic premises

and is not meant to be used by the people who live in the house, then 421.1.201 applies, whether it's attached or not.

Fair point.
There was an article in one of the trade journals considering this. It suggested there may be a case for not applying 421.1.201 in out buildings that are not directly attached to the house.
But it depends, like so many things, on how we interpret the regulations...

Hard to think what that case might be apart from "we don't want to have to apply it."

I tend to come down on the side of "interpreting" things on the basis of what the actual words are and what the definitions of those words are.
