At my place of work we have just had multiple LED advertisement screens fitted outdoors, the company specified 16amp RCBO’s for each set of screens. On powering up, the circuits were nuisance tripping due to earth leakage. So the company who installed swapped the rcbo for MCB’s.
The screens themselves, and the frames they are mounted on can be touched by the public but the commando plugs and wiring cannot.
In this situation, is it acceptable to use MCB’s and remove the use of RCD’s due to nuisance tripping as the screens themselves are only going to be operated by skilled persons.
Some of the circuits have over 100mA leakage.
Installing more circuits would help but these screens are pre made in sections to accommodate a single 16amp supply. This would be up to the manufacturer to resolve.
