Hi, all,
I’m looking for opinions on earthing arrangements for a project I’m involved with. The site is 60m by 60m and will involve ten houses and flats. The supply is at the site boundary and is a Bemco Board with metering for each property with a 25mm SWA 3 core to each via a switchfuse. The earthing is PME. Although there is bonding for the internal gas, the gas supply pipes like the water are plastic, so probably not an effective bonding path.
This would leave the whole site effectively relying on one earth point at the Bemco board. Whereas it’s not my decision on the job, I’m not comfortable with this. Any thoughts?
Thanks.
