Refence method, disagree meant on a job

[Jimmyb]

hello, What ref method would you class this cable there will be 100mm of king span to put in but the cable will be above the king span by 10mm or more so not in contact with any insulation.

thanks

101, clipped direct with no insulation above.

 

[Jimmyb]

isnt 101 covered by insulation exceeding 100mm

 

[telectrix]

think that's 103

 

[Jimmyb]

103 is in a stud wall with cable not touching surface, are you saying the cable is classed as ref 'C' clipped direct

 

[telectrix]

sorry 101 is insuylation not exceeding 100mm. 100 is what i shouls have said for no insulation above

 

[telectrix]

oh. p265 brb. eyes too tired to read.

 

[Jimmyb]

just got on site guide out and 101 is insulation exceeding 100mm, 100 is insulation not exceeding 100mm, and c is clipped direct.

are u saying it's clipped direct or insulation not exceeding 100mm

thanks

Clipped direct if not touching,10mm enough for heat to dissipate. What circuit is it for?

 

[Jimmyb]

kitchen (extension) radial, builder's sparky reckon it method 100 so will have to be made in ring which is sort of problem cos bathroom floor has been tiled now so hard (impossible) to get a another cable though but could use shed cable as its also 4mm and run new cable outside for shed but i was sure its classed as clipped direct and didnt want a cable on outside of building if possible.

 

[SimpleSimon]

If it's 100 why do you have to ring it?

 

[Jimmyb]

because 4mm with ref 100 only takes 27amp and wouldnt want a kitchen on any less than 32amp

just woke up. re-read post correctly. cable is not covered by any insulation, so therefore its method C , clipped direct.
