My condenser tumble dryer keeps tripping the main 80A switch on my CU.

"Switch"? I think you mean RCD as normally the "main switch" in an CU
has now fault or overload function it is just a switch.

yes RCD (sorry)

Assuming that it really is an RCD the the chances are that the dryer
has an earth leakage fault, this is fairly commmon. Probably have to
repalce the heating elements.


replace dryer is easier I think :-(
