Hot
dimmer switch! Somebody asked me today why a particular dimmer switch in
their house gets very hot. The IET wiring regulations allow
non-metallic parts that are intended to be touched (but not hand-held)
to be no hotter than 80deg C - so the hot dimmer switch could be normal.
However, any appliance cannot withstand infinite energy passing through
it thus a dimmer is rated to a maximum wattage eg
250W. So 8 x 40W GU10 lamps (in an array of downlighters for example)
would exceed the capacity of a 250W switch. Prolonged heat in electrical
parts can, over time, break down the insulation and ultimately cause
dangerous shorting and potential fires. Check that you're not
overloading your dimmer switches. Incidentally modern dimmers work in a
very clever way - more about that some other time!
