Hi All i know its late friday, but try and help me out with this one if you can.
Just got in now from work on the way home a landlord called me to ask if i could test a communal DB he has at an HMO.
I decided to have a look on the way home, long story short each flat was feed from this DB including the communal circuits(lights,sockets).
so i checked Zdb to each flat which was ok but when i did R1+R2 test on the supply cable to each flat i got nothing,tried to each flat and 4 out of the 5 came back with a zero reading.
Distribution board was contactum,each flat was feed from a 40 amp b type mcb (No RCD on DB).
Any thoughts as its got me wondering, the Zdb to each flat was ok but R1+R2 no reading at all.
Don't mean to deflate anyone, but it's hard to say really without actually being there !
Let us know Delboy
Are you sure the circuits are labeled correctly???
i.e you linked r1+r2 at DB circuit labeled flat1, testing at flat 1 but the r1+r2 circuit is actually flat 4?
