New install for social alarm system PSU

Stewart Mason

Hi

I'm going to let the photo speak for it's self. The RCBO is powering a PSU with battery back up, which is powering a social housing alarm system. All the equipment is mounted in a steel cabinet on the outside wall of a bungalow. The supply is a TNCS.

All comments will be gratefully received.

Thanks

    £8 could have been saved by using an MCB instead of the RCBO.

    Or £20 could have been saved by retaining the ordinary main switch.

    The RCD main switch may trip on a surge or even be damaged by it.

    That's my concern, the main RCD tripping due to a surge. I have raised this with the consumer unit manufacture - they have not replied.
