Is there a MCC maintenance manual, containing an "as built" drawing of one, nearby?

Hello Slackie,

Did you solve that 'star delta motor running in reverse' problem of yours?

There was enough information from CR4 respondents for a correct answer, thanks.

Actually, one can do it by looking at the colours of the wires at the motor terminals. There should be (in a BS7671 installation), two browns, two blacks and two greys, arranged as two cable-sets of three, one of each colour in each cable. All that is needed is to swap the black for the brown on both cables.

"Static," as in no moving electro-mechanical parts, such as one might find in a semiconductor version of a relay? 'Splain yourself, please.
