Hi all

I am currently testing a lot of 110v/ac circuits. These are fed from a db which is supplied by a 110v transformer. the MCB's are double pole 6a 60947 schnieder.
My questions are: 1. What is the max zs for the device? 2. do I need to put anything special on the eic forms

Thanks
 
There are tables in bs7671 that will give you max Zs for 110V circuits or you could always calculate it.
 
What research have you done in to the situation so far?
I have got 110v readings for 60898's but I'm struggling to find anything for the double pole type 60947. Its not something I have ever had t do before and I'm not sure where to start. I had a look at the technical data for the schnieder stuff but either I have missed it or its not there.

Cheers
 
Is this transformer feeding at 55v a leg? If so you will be looking at different values.
