Whilst dismantling an old household appliance, I noticed that the motor start capacitor is prominently marked as being 'P2 PROTECTED'.
I've had a quick look on the internet - but whilst I can find many manufacturers offering capacitors with P2 protection, none really explain what the protection is or where it is required.
Is this something similar to Class X / Class Y capacitors as defined in BS EN 60384 or is it something else entirely?
