[QUOTE="ProDave, post: 392794, member: 6969"] I'm not sure that reg is the reason for 3 metre meter tails. After all the tails from the meter to the CU are rated for the full supply current and protected by the DNO's fuse regardless of how long they are. And there is no change of CSA involved either. It's an additional isolator you are required to fit to long tails not additional OCPD so it's a different rule entirely. It just happens to be the same 3 metres. [/QUOTE]
