Connecting 6mm SWA to 2.5mm T&E in an FCU

[iaredarren]

I’m looking at powering a small garden office with a spur using 13amp IP66 External FCU. I want to use 6mm SWA from the FCU to the garden office as the run will be 75 meters and I’m therefore concerned about voltage drop (though I will likely never draw above 9 amps). But I can’t find an FCU with terminals for 6mm and 2.5mm.

Anyone aware of any FCU’s that have adequate terminals or is their another way around this that won’t involve the addition of junction box?

IIRC BG storm products accept 1x 6mm cable

Thanks. But where it says 1x 6mm cable, does that mean it can’t take a 2.5mm in addition?

The 6mm² and 2.5mm² would be in different terminals - 2.5mm² for the supply and 6mm² for the load.

Are you sure you should be contemplating doing this?

Thanks. I was early reading the specs incorrectly and didn’t realise the terminal capacity was just referring to the load

Why do you say that pal?
