did rings max length/area covered go from being 100msq area to 100m cable length?

 
Its not a specific reg as such ..

just general good guidance...

e.g. the picture of "typical Ring" arrangements found in

Appendix 15

page 362

bullet point (iv)

"taking account of the total floor area being served.(historically a limit of 100m2 has been adopted)"
Max length would be more limited by R1+R2 and its effects upon Zs value, volt drop etc..

which are related to actual compliance with certain regs.

 
Spec Loc has to hold the crown the some of the best explained, well referenced answers we've had on this forum.He's been here from the begining.
Agreed.
