Yeah as an ex mines bitch i know downtime costs....

u know what costs more.... waiting for the mines inspectors to show up, having the mines coroner on site and trying to get replacement bits from germany coz some bright spark figured they could "hold" the breaker in till the machine cleared the jam.

If it can be reset, only if there is no exposed live wiring, then allow one or maybe two resets a shift before you must call a tradesman, log all resets and note them in the handovers and to maintenance personnel.

I agree with the majority, if you need tools to get to it then it ain't user servicable, and around here (oz) qualified in electrical tends to mean licenced AND competent, and one licence doesn't cover all.
