40 amp type 4 3 871 mcb

[Tosh]

hey guys can anybody shed any light on this problem. i am carrying out remedial work from a periodic inspection , carried out bye another company. they have put max zs 1.15 for 40 a type 4 mcbs , a know this is wrong and the higest measured zs is 0.34.. currently theres 8 way 3 ph D.Bs with these mcbs controling sub boards (1 ph). the company has put these done as a code 1 suggesting all boards be replaced, i don't understand why this would be recommended , can anybody shed any light on this.

I suspect that thereason for the Code 1 is that they want to get some more business

Touting for work.

If the existing board is in good order and the max Zs's meet the max for the type of MCB, then there should be no reason to condemn it. Certainly not just because it's obsolete poduction.
