My MCB for my workshop/garage is tripping, at what I would expect to be less that the rating of the 16A breaker.
In the house CU, there is a 16A MCB for the garage. In the garage, I have a CU, with a 16A MCB for my workshop.
When for example I have the Vacuum on for dust (the 1100W High Filtration Dust Collector) when I start my table saw, the DeWalt 7485 which is 1850W the MCB in the house trips. No matter which way round I start them up, the MCB in the house trips. There is no other load on the MCB, other that the two items.
Being nearer, I would have at least expected the MCB in the garage to trip, but this isn't the case.
2950W, at ~240V I make just over 12A. Obviously I know the start up current might be higher - but should I be expecting this to trip?
