Fault current

[Farmelectrics]

Can someone explain why fault current is higher when your zs is lower trying to write down reason but struggling on what to put

Really, I think you'll find the general B type breakers are 6kA, although with back up protection of your main fuse you'll get away with up to 16kA

Well all the MG ones we use are rated for 10kA anyways
Granted there are 6Ka out there to

I bet they're type C, the usual "domestic" type B breaker is rated at 6kA....Icn & Ics

As a general rule of thumb nearly all breakers designed for 3 phase DBs are 10kA, and nearly all designed for domestic CU ranges are 6kA. You will get interchangeability with most manufacturers though.
