This summer I intend running electricity to my greenhouse for power and
light.

It's about a 35m total cable run from a dedicated breaker on my distribution
board and will be 4mm Twin/Earth (inside) and SWA (outside/buried).

It can be a pretty moist/condensing environment so I have already installed
some IP65 fittings like this:

My first thought was to use MK Masterseal switches and sockets in the
greenhouse, with a local master isolation switch like this:

Question is should I separately fuse the sockets/lighting circuits in the
greenouse or not? Since the whole installation will effectively be an
RCB/MCB protected "spur" is local fusing necessary at all?

Thoughts appreciated.

I did a provisioning for the greenhouse last year and used Masterseal
components for all the outlets and components.

The power outlets are obvious enough.

The Masterseal range includes a lot more components than TLC carries
(or shows on their web site.

I used an FCU unit into which I fitted a 3A fuse as a way to protect
the lighting parts, but cabling from it at the back rather than
through the hole in the front plate.

Also in the range are empty boxes that can be used as junction boxes
and a neat job can be made.

I used IP65 fluorescents as you have as well as some low voltage
halogen lights which run from an IP65 transformer.
