A simple question!

Hello all,
Just a quick one; what does the term " high integrity" actually mean in regards to a CU?
What is the the difference between one which is high integrity and one that is not?
Thanks in advance,
Gerry.

Difference seems to be around £20-30!

From experience - but not necessarily the defiintive answer - I'd say it was flexibility of bus bars.

Put in a Wylex NH box - dual RCD etc - but couldn't put in a RCBO just to supply smoke/heat detectors. Wylex support line said the NH HI version allowed this as you have a spare neutral bus bar. This was a NHRS10SSLHI, by the way.

As I say, not sure if that's the full answer - I'm interested to know too!

High Integrity can be configured a number of ways. They have 3 neutral bars so you have 2 for the RCD's and 1 for MCB's/RCBO's off the main switch. I think thats about the only difference

 

[ezzzekiel]

allows rcbo or unprotected ways as well as standard split load dual rcd
