In my entire three decades, I only ever got called out to one consumer unit that started melting then smouldering due to a loose connection on a shower MCB.

I witnessed one when I was a student. The landlord had upgraded the shower over the summer; one of the flatmates was using the shower for the first time and the rest of us smelt a burning plastic smell from the cupboard under the stairs. On opening the cupboard door, we saw a molten plastic CU, with the plastic literally dripping off and the bus bar exposed.

I think I agree with that, the overheating always seem to be the isolators loose joints.
