Ring circuit cable length

How would I go about bonding copper earthing wire to the rebar, isn't this going to corrode (more) quickly due to the potential between different metals?

Can you use Wylex double pole RCBOs to avoid an upfront RCD ?

We don't have wylex here. I only found hager single pole rcbos. I put a 100 ma rcd infront of the rcbos. So I'm thinking the 30 ma rcbos should trip before the 100 ma rcd.

TLC sell them online if you need them in the future.
