I’ve always been alright with the knockouts provided for Fusebox consumer units but I’ve got a job coming up where I don’t want to use the large 32mm or 40mm knockouts.
I’ve got a 10 way board consumer unit to fit and the knockouts are so annoyingly spaced out, you could fit another 3 knockouts on the top if someone with common sense actually designed it.
I’ve never had to drill the knockouts and I want to know if I drill a 20mm hole centre of the 32mm knockout hole is the 32mm knockout going to drop out on me leaving me with a gaping hole I have to try and downsize or will I be okay if I drill it with low pressure and a sharp hole saw?
As they haven’t spaced it properly and I want to allow space for other knockouts in the future… what if I was to drill off centre so that my hole saw is cutting through the circular edge of the knockout will the knockout dropout?
