Who can install a PME system?

Yep its down to the supplier , i would investigate why you cant get a good reading on TT maximum is 200 ohms unless you are on a very dry area or sandy change you earth method or add say a earth tape or plate try additional Rods

unless your NIC then its 100

100 ohms is only their reccommendation, it's not a requirement, they haven't rewritten the BRB.

are you sure he didnt say if the PME ze was not great he would put in a TT to accompany it I believe this is acceptable.

the max Ze for a TNCS installation is 0.35 if you get readings higher than that then you should contact the DNO , to investigate this as it could be a fault on the supply ,

[DurhamSparky]

i just did 2 PIR today and well i walker out of one with 150 quid worth of Visual work (sockets off walls spur from spur etc) that i completed at same time as a 13 circuit PIR and then coded a 4 for not having marked switch wires!! lol!! lazy ness on my side as if i could be bothered i would do them but i was busy!

and then the next door house (same landlord) no visual defects apart form Pendant showing cores from flex i had a list of 3 and 4 from 3 circuits!!
