Is the landlord paying for the spark but your paying for the work? If your paying you should be able to get whoever you want

landlord is paying for the check / test as weve put the new supplies in for our equipment any changes / not upto regs are coming out of my pocket

same goes if anythings wrong with his side he has to pay

 

[Corbs]

right had an hour to spare

tested from the earth point in the isolator (spot welder end) to armoured sheath and got continuity

other end tested from earth point on the fused supply to the armoured sheath and got continuity

now tested from earth point in the fused supply to the met and got continuity

my question

from the met to the earth point in the isolator (spot welder side) via a fly lead what resistance roughly if any am i looking at

 

[telectrix]

all depends on the csa of the cable or the armour and it's length. figures can be obtained in the osg.

Your looking for a low resistance, if you have a multifunction tester I'd advise you carry out a Zs as well

ta will try and find the table

what sub 5 ohns ? and dont have a mft (not a sparky)

 

[telectrix]

what are you measuring? a core conductor or armour?

earth path eg from the isolator by the appliance to the met

as the testers say theres non / not upto standard

 

[telectrix]

as i said, the resistance will depend on what you are measuring. what size MCB is feeding the circuit? e.g. if a 32A type B, then i'd expect the resistance to be less than 0.5 ohms.

no mcb but 32amp replaceable fuses (i think there type 269)

 

[telectrix]

so definitely less than 0.5 ohms, depending on the external Ze could be less. no way to determine without using test meter/s

thats fine least i have something to go off

I can not see any earthing conductors at the mains intake.There is nothing wrong with using the trunking and conduit as the C.P.C. but I can't see how this is earthed back to the consumer unit.
