Supply to garage

[holmes571]

Hello All,

Just looking for a little bit of advice/ opinion as I am a bit undecided as how to complete a job in my own house. Looking at putting power supply into new garage running 4mm T & E from consumer unit up in a void, under bedroom floor to adaptable box on outside wall then changing to 4mm SWA and carrying on to two way CU in garage. Would you put RCD at house CU or garage CU. Submain will not be entirely SWA and will be under floor in house so needs RCD protection but I dont feel comfortable with no RCD in garage for some reason. Anyway my question is where would you put RCD house or garage. Supply in house is TNS and garage is about 3 metres from house.

Any advice welcome.

Thanks

do the entire job in swa and you'll only need an rcd in the garage unit , which will work better than having to walk back to the house to reset the rcd if it trips.

Why does a cable 'under the floor' need RCD protection?......keep it > 50mm from the top.

Hope the voids not a cavity wall....

Agree.
Or use an RCD upfront and Hightuff cable straight into a 2-way CU in the garage.
Lots of ways to do this tbh.
