Ok, most new Consumer unit seem to come with a 63A RCCB and two MCBs. Most house consumer units now will also have RCD of some type be it a dual board or RCBOs. I know there can be issues with Selectivity having an upstream and downstream RCD. One Should really be S type (more expense). Should...

Hi all, what is the best way to configure surge protection in domestic dwellings when you have multiple consumer units?
Does each consumer unit need it's own spd, or can I fit one in parallel with all consumer units?
I have a 20m run from meter cabinet to two consumer units in house, then...
Cascaded Distribution Units.
Given how cheap populated distribution boards are; i've started to use them for almost every major junction in my home:
Domestic Main Distribution Unit >10mm swa > Garage Distribution Unit > 6mm swa >Spa Distribution Unit...
Thought I'd give one of these a go.
Very easy to order and they build the board for you in the order you want. Next day delivery was free.
First impression is that it's very solid and the front comes on and off easily.
(So much space!)
When I fit it, if it doesn't look too rough I'll post some...
Generally, we would use the Wiska box. A couple of times apprentices have asked whether it would be OK to run a 6mm cable and join to the original ring mains in the Wiska. If the Wiska box is accessible for future R1+R2 testing, is there any reason this can't be done? My instinct is to say...
This in a kitchen/dining area of maybe a little over 200 sq. ft. (10 x 21ish). Presently have 4 flourescent troffers with standard 2 40w lamps each, mounted in the drop ceiling. Pic is attached. Want to convert over to LED troffers. I would not want any more brightness than I do now, and...
I am about to quote to install this HRU. Having never fitted one before I had a few questions?
1. How long roughly does it take to install? The 162mm diameter hole will already have been drilled. There is a socket very close by and it will be in trunking, so easy. It's more the length of time...

Hey All,
So query I have had for a long time is this:
Why supply special entry glands for a metal unit (top and bottom) to help stop the spread of fire/dust ingress/water/fingers etc

Hi,
I've got to put in an additional consumer unit into quite a large property and rather than daisy chaining them back to a single MCB in the main board which is RCD protected, I wondered if this a better solution: The property is served by TNC-S with an isolator switch.
Connect new tails into...

I've completed level 2 and 3 fulltime in college and recently started doing the performance units. Am I meant to be given a question sheet or a handout of some kind? All I've been given is a "performance assessment criteria" leaflet and a job report example, which seems to answer questions...
