What lighting and power cable for a potentially moist environment
Before anyone replies with the usual "Get a qualified electrician...." - I have booked one but he's very busy for a couple of weeks and so I want to route the cable inside the walls and behind the skirting myself and have him just do the connections.
Environment: Outdoor insulated wooden cabin that will house a hot tub and powered exercise equipment.
The main power cable has already been supplied by the electrician and buried under the concrete leading to the cabin.
I need to know what's the best and safest cable for this environment for the following:
4 wall lights + low voltage external recessed lights on a 2 gang switch;
6 power sockets.
The hot tub will have its own dedicated power supply so is covered.
Be very careful is the answer and not for the reason you may expect.
The electrician may lose his registration with his chosen trade body for signing the certification if he did not do the wiring himself. Check with him first and if he says that it is okay, then maybe you should use an electrician that rates the value of his signature rather more highly.
This is not a sleight in anyway against you, but would you suggest running in the gas-pipe in your home ready for the gas-safe man to connect?
Tens of thousands more people are injured and die through electrical faults than through gas faults.....I wonder why that is?
I hope you don't see my answer as too negative

By doing some of the work yourself you are taking on a liability under part P of the building regulations and also are in effect acting as the designer for part of the electrical installation.
Without being harsh, breaching part P of the building regulations carries a £5000 fine, plus it's illegal for an electrician to sign off electrical work installed by other people.
Best option is to wait until electrician can complete the job themselves rather than try and help out and save a few quid.
