Hello all,
Theoretically speaking, so I can get an idea of cost...
My garage is about a 20-30m run of SWA 2.5mm2 cable from the house. This connects into the main CU on a 16A MCB. The garage as a small 4-way CU in it. Theoretical current limits on the 2.5mm cable indicate it should handle in excess of 20-25A.
Unfortunately I’ve inherited the situation, it isn’t easily upgradable, and I have no idea why the garage wasn’t installed with a 6mm+ cable originally.
Is it possible to install a 16A device in the garage on its own MCB? Eg. A 3.7kW EV charger.
If so, would it be just the case of upgrading the MCB that serves the garage to a new 20A MCB (perhaps Type C) in the main CU? And putting a new MCB in one of the spare ways in the garage?
Thank you
