    Under what (if any!) circumstances is it permitted to run two separate cables to make up the conductor surface area of a larger cable (which, in this case is impossible to install... Need to change 2 6mm radials for a single 10mm, but it's going to be near enough impossible to draw through a...

    If you’re on a job which involves things like just replacing light fittings and odds and sods on different circuits for the same client, is there a MWC that can cater for more than one set of circuit tests rather than doing separate certs for each circuit?
