I don't think i explained it that well mate, i'm talking about the main switch for the consumer unit, the value is needed for the cert thats all.

not come accross that one before, its not an protective device is it? if it s just an isolator, why would you need the short circuit capacity?

Shakey need your hekp on this, just got kewtech schedule of test results, the cert you fill in all the test results on, and ther is a box with "overcurrent device short circuit capacity" in KA. I was told this was the capacity of the main switch of the cu, is this right? If not what does it mean. Thanks.

aahhh, i can see now

like i said the main switch is not a protective device

the overcurrent protective device for the installation is the suppliers fuse (often a 1361), they quite often have the Ka value written on them
