No offence, but when i have to make an effort to read your post, and decipher the text talk.... I lose all motivation to help.

No sparks (to the best of my knowledge) own an enigma machine.

You have a full sized qwerty keyboard in front of you, no limit on characters, use em!

i had an enigma or was it an enima, either way i agree with gstuey, lost interest mid sentence

I also read it as soon as it was posted and had the same opinion.

must admit it confuses me because of the text talk. and because the original poster askes 3 times explaining each time what he wants. (as if we are thick). lost the will to help.

Lenny or anyone else that knows, for the purposes of an on site assessment by nikky if asked to refer to the max Zs values would you refer to the BRB or the OSG ambient temp adjusted one's ? I ask only because the spark I am getting some advice from for registration seemed to think the inspector would like to see that you know your way around the big red book ?

 

[SirKit Breaker]

I bet his certs look good written in all that bollox

 

[Guest123]

It asks for max permitted values by BS 7671 not OSG or anyone else.

If the question gets asked you could say that you use the BS 7671 values on your certificates but also mention that any calculations you do are compared to the 80% corrected values in the OSG.

They love that kind of thing do the assessors.
