We needed to install some new equipment into a switchroom, the issue we faced was, there was no more spare room in the MCC panels. On closer inspection, there was a redundant variable speed drive taking up space – so it had to go.
The motor was still in use, so I had to carefully plan exactly what needed removing and how it needed to be done. I put together a plan (parts below).
I find one of the biggest mistakes people make when planning jobs for others, is to give them a final design, without telling the poor electrician how to do it. As you can see below, a good plan clearly shows the original wiring, and the changes required – in a simple step by step solution.
