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...
Firstly, thank you for taking the time to read this. I am not trained in electrics whatsoever, I am a just a home owner looking for advice.
I have a flat that I would like to improve the EPC rating on. A QS has advised that I need to install High Heat Retention storage units and a dual...
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...
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...
Hi,
I've just landed a job as an electrical tester and need a new MFT (mainly light industrial).
As I'm going to be spending considerable time testing I thought I'd ask about the new high-end options.
what are peoples favourites?
Are these new fancy options like Bluetooth on the mergers...
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
then go and have a bloody great big knockout at the back which only needs a grommet strip to protect the...
Hello everyone,
I need to supply power from an A/C wall plug to an enclosure containing 2 power supply units.
These are:
1 - Switching Power Supply INPUT 100-240v 3.0A / OUTPUT 5v = 40A --> connected to LED lights
2 - Power Supply Unit INPUT 100-240v 1.5A / OUTPUT 5v = 10A --> connected to...
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...
Hi guys.
Just need pulling into check on this one. I’ve been asked to wire an extension including new lights and sockets and SD’s ran from existing circuits in the house.
Now his mains was fitted in ‘15; a split load RCD mains, located in a hallway of plastic construction.
I’ve always...
Hey guys, been trying to find via google the bespoke/custom made consumer unit manufacture with no joy, can anybody remember what the company was called? or better yet have a link?
cheers
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...
My daughter has ground floor flat, there are four flats on each floor. The consumer Units for each flat are located just outside each flat in the communal hall way, Is this against the Regulations?
What is the story with them? I thought they were being discontinued (not sure where i heard that tho). But recently i noticed they were selling SPD models that i had never seen before. Have they had a change or heart or is this still old stock?
We have a Electrical PLC Control Panel that has to supply 45 Fused Spur units, do I need to protect these with an RCD, we have a 10A Type D MCB at the moment.
Each Fused spur controls an electronic Volume/Pressure controller which is rated at 130mA.
