Which type are people using on both input and output sides of dimmers? I seem to recall someone having a problem with a type B tripping due to inrush when powering a LV transformer. Got an install coming up with lots of LV so I would like to get this right first time:) On a related note we are installing MCBs on all outputs now, partly for protection of the equipment but more for the ease of isolating LV transformers, fans etc when they need repair or replacement.
