[QUOTE="stevesown, post: 489381, member: 32061"] Hi all, I have a customer with a metal box type Wylex consumer unit, which presently has a NHXSBSB16 breaker feeding a small pump set which is just fed Direct Online. I need to swap to a Type C breaker as the new pump set is powered by variable speed drives. The question I need answering is:- Can I put just a normal type C breaker in the consumer unit? as the RCBO types normally trip when you connect variable speed drives due to the characteristics within the drives.
