Just had an extension done. The builder's electrician wired the extractor fan in the utility directly to a ring main via a 20A DP switch ie no fuse. When I queried this he said no fuse needed because 2.5mm cable used from switch to fan. He signed the work off and now have building control certe from local council for whole extension. Nothing from electrician himself - told by the builder that the electrician certifies online with NAPIT and then council issue the certe.
Still not convinced though - I think there should be a fuse to protect the fan? Now worrying about the general standard of the work. In particular no RCD on the new lighting circuit he put in for the extension - it serves the shower room including a light in the shower cubicle. Is this right?
