IR on the ring may be a red herring, if the boiler is on a seperate radial.
However, the boiler is new, so is the fault, and coincidence is not a friend of mine. I would try to eliminate the obvious. The boiler could be triping the RCD even if not fed from it. Usually this is an N to E issue. Also, bad joints and connections can spark, which can trip an RCD on an adjacent cct.
However, if disconnecting the ring stops the trip, does disconnecting the boiler do the same?
If the trip takes 10 mins, do a ramp test to see when the RCD trips with all on, none on, and one only of each cct on at a time. This way you will find the leakage of each cct, and it may point to the dodgy one.
Where was the boiler before, if it is on the immersion now? I presume there has been new bonding, any issues there?
Silly question, are you sure you have the N and E of each leg the correct way around?
