Firstly hi all not posted for a very long time for one reason or another, hoping to be a little more active on here as and when i can.
As the thread title suggests my query is regarding a HMO that i am currently working on completing and EICR.
First day here today after a previous site visit, the setup is pretty straight forward with 10 rooms in total, each with their own meter/consumer unit.
Each consumer has a total of 3 circuits, shower, sockets and lighting. And each consumer unit is a single phase supply, in turn supplied from the main 3 phase DB via a 63a 60898 type B MCB.
The supply to each consumer unit is in 16mm t&e and this is where it gets interesting. It doesnt seem that at any point the t&e is ran where RCD protection would be required. All in ceiling/loft spaces and clipped direct where it comes down into each meter. However one of the first things i noticed was the c.p.c within the t&e had been cut off.
Further investigation revealed it had been cut at both ends so the t&e sub main had no c.p.c present. Each consumer unit does have what looks like a seperate 10mm c.pc installed and test results confirm that there is an earth present.
Whilst investigating this it became apparent that the separately installed 10mm c.p.c was in fact ran as a ring from the Main DB around to all the consumer units.
Im trying to justify what to code this and even if i need to give any code. Any help/ advice would be most welcome
