My brother has an intermitttent faullt on his ring circuit, with the mcb tripping, its an old board with mcbs and an ELCB. His supply is from a pole in the garden , TT system i thought with earth leakage protection, but he has had a spark round ( tripped twice today ) who reckons its a PME system. All i have seeen at the cu is the incomers and a 10 or 16mm earth cable cable tied to these ( which may be earth bonding ) but would the supply company use oh cables for a pme system, and god knows who you phone up now for info.
