Hi all,

I'm laying the cable through my floorboards for a new garden lighting circuit, which I will have wired into my new CU (by an electrician) and on an RCD protected circuit. I've previously had advice here and will be using 2.5mm TE cable for the internal parts of the circuit. However I wanted to check if I could use a Hager J804 20A maintenance free junction box to branch off different lighting groups? All lights on these circuits will be 5W LED bulbs. The circuit will come out into my garage through an adjacent wall and into a CED IP65 24A 5-Terminal Weatherproof Outdoor Adaptable Box (I appreciate it's indoors but wanted to use this anyway), from where it will branch off to lighting groups at the front and back of the house.

Thanks in advance.

Yes, you may use a J804.

What made you think you might not be able to?

If in an accessible location you could use virtually any type of junction box.

Garden lights are prone to moisture ingress which can result in the RCD tripping. Other circuits on that RCD will loose power. The RCD cannot be reset until the lights are dried out,

A double pole isolator should be fitted to provide full isolation ( Live and Neutral ) of the lights when necessary. Then the RCD can be reset without the need to immediately dry out the garden lights.

Thank you, I have that in plan. Each light cluster or group will have a DP switch in between.
 
Can I also confirm whether there is a requirement to screwdown the MF junctions boxes when they are used under floorboards? Currently I have mine resting on the plasterboard for the ceiling below.

Should be no need, providing the cable sheaths are secure under the provided 2 screw clamps
