Hey guys. I am currently studying for 2396 city and guild electrical design exam and I'm stuck on this question. Its asks to determine the residual current rating of an RCD in order to comply with regulation 411.4.204. The circuit in question is a final ring circuit protected by a 20a type C...
If the max Ze for Tncs is 0.35 but you had a 1361 60amp fused isolator before the c.u with the 1361 having a max Zs of 0.56 (from the 80% chart) if the recorded reading at the c.u was let’s say 0.47 ohms would that now be considered to comply? i can’t see why it wouldn’t.
Hi guys wondering what's the best way to do this got a board change on a TT system 3 bed terrace. So we need to offer an SPD however can't have one in a metal C.U without RCD protection on the Tails because of the single insulation feeding the SPD. So to do that that we need an s type RCD...
Manufacturers want there fans fused to 3a on the permanent feed but the switch wire is still on the 6a MCB doing an eicr is a c2 if there is no RCD protection
The above statement was made in an EICR which I was asked to look at. In my opinion they are on the wrong side of Trading Standards to suggest that an installation should be re-wired because it is not up to current regulations. If it is safe then I would not suggest to a client they must have a...
Just carried out an EICR on a standard semi which has had some work done in 2015-16. The works included connecting an outbuilding to the rear of the house to create a hall, WC and utility room. The Kitchen was also replaced, new cooker and shower circuits installed.
The 1 sockets circuit does...
So I was in a new build today - signed off 3 months ago...
No surface trunking, all cables in walls and ceilings ..... the OCPD's for circuits 1 to 3 look wrong to me
Discuss!
Been at a place today.......... brand new loft conversion.......... so an additional CU has been fitted for the lights and sockets ......................
Thinking specifically about 314.2 :
I would say that it doesn't............
Opinions please
and more to the point, this conversion...
People,
First post as new to the industry and the forum. Would like thoughts on wether members would consider the following scenario would comply with regs, particularly 434.2.1.
Bathroom in a 2 story detached house is being renovated. An electric shower is being removed from the bathroom which...
hi all
thanks in advance.
as above states, iv come across a very old shaver socket and i know iv seen in the inspection schedules something about when a shaver doesnt comply... just wanted to know a little more about this?
the shaver socket is about 20 years old, has a switch for on/off so...
Been to look at a job and the customers consumer unit is split load 100a 100ma time delay rcd, which is acting as the main switch and 80a 30ma rcd. Upstairs and downstairs lights are protected via the 100ma rcd, with the rest of the installation via the 30ma. Ive been asked to do some work on...
Hi All
Do the MK Flush consumer unit comply with the new Amendment 3 of 17th Edition?
Metal back with a plastic front????
I'm looking at installing this one into a flat conversion I'm doing as we speak.
Working in a kitchen, and just thought, there's a shower in the corner! albeit it's like a separate room, but checking the osg can't see this scenario. I think it will have a normal shower door, and you step up into it, but the kitchen sockets are within 2m of it. It's an old Georgian house with...
Hi Guys
I'm sure this has been brought up before but I'm unable to find the answer I need. I was to believe ammendmant 3 regarding metal consumer units kicks in on the 1st of July, I have a board change lined up in July and someone told me today that they have extended this date until December...

Doing some testing today and came across something I was hoping to get cleared up.
The maz zs of a c type 16amp 61009 is 1.44 ohms on table 41.3 however on table 41.5 it states that a 30ma 61009 under 32amp can have max zs of 1667ohms.
Would you write on test sheet maz zs 1667 ohms and...
During a moments reflection after last weeks visit to CEF to have a look at the Klein stand. They had several multimeters on show, not MFTs just the normal type Volts, Ohms etc, and before you have a go, yes I forgot to ask the Klein Rep, mind you he probably wouldn't know what I should have...
Hi all,
Just wondering if anybody knew why the max number of sockets you can have on a radial circuit covered by a 20amp breaker, and fed by 2.5 T&E in order to comply with regs?
