Tripping unit

Alasdair Anderson:

The device is one of three CBs inside a new main panel  which was constructed by local panel builders under instruction from a consultant. 

So who is the designer? It sounds as if there is a grey area between the panel builders and the consultant as to who is actually the designer.


The tripping unit is an electronic (which nowadays means computer) one, as far as I am aware, and therefore there would be no thermal priming as there would have been in the old days (showing my age here) so it should not matter what the previous current has been as far as tripping goes.

 I am showing my age Alasdair! I don't know how many times I have been told that and still it doesn't stick! 

Ah, the designer? Well I wouldn't be one for love nor money! I don't think the industry gives them the credit they deserve. The consultant is a lovely chap who seems to work on his own. It does appear that the correct details were not passed to the panel builders. Whoever is to blame, lets hope they have adequate PI insurance in place!
