SWA into meter box

[cor]

query

 

i have 3 core 10mm SWA coming from garage to consumer unit and was thinking the best way to do this?

plan was a junction box  to terminate SWA and then feed double insulated meter tails into meter box to separate / or dual pole henly blocks

the meter box wont fit a meter box fuse switch like:

Lewden 100A 1+N 100A Metal Fused Switch - Screwfix

 

but i would just fit this type instead.

Click Scolmore DB700 80A Fused Main Switch | Toolstation

 

garage will have its own CU - i have 10mm SWA about 26m(12m in a trench) to feed lights and ring- may have a compressor and welder in there for  basic car repairs , mid height lift potentially, no EV but space will be left on a CU for it.

 

electrician will do all the formal connections/ testing / reg with council but was just sorting all the cable routing to the meter box and garage

meter box attached for info

 

TIA

Have you done voltage drops calculation for expected loads? Sounds a bit small 10mm²

i did a estimator on tlc and pretty sure it came as 10mm.....should it be 16mm.. or more then

worked on the premise that not all equipment will be on at the same time- havent bought any of the below yet

so its just lights and plugs and electric roller doors atm

 

compressor 2200w

lift 2200w

8000w welder

7700w ev charger- dont have one anyway more for later if ever

lights are led 180w

used 10kw as a power

Isn't the norm for motors 4x rated capacity? All the equipment you have listed I would be doing 25mm².

I was going on the lines of the initial start up of motors being high demand less after and needing a type c rcbo or mcb...

 

And not using 2 at the same time.
