Hi guys.
im second fixing someone else’s first fix and it’s been wired different to how I’d do it.
Got a two way in the lounge, at first switch I’ve just got a feed in & out and strappers. Second switch I’ve got strappers and switch. I’m going to use the grey from the strappers as my neutral...
Hi, looking at installing a sub main down to a field to supply caravan hook up points. the supplier has stated they are installing 2 x 100 amp split phase 180 degrees apart. not worked on 460v/480v split phase - my question is how do i go about sizing the neutral. i plan to run a steel wire...
Hi, I have an old style fusebox and planning to replace (via electrician) with a modern one (wiring was uprgaded by previous owner) and I noticed when removing a spur line to the outside that was not going to pass muster that my multimeter was showing that earth and neutral were connected. I...
Hi. Turned power off to change a socket front. Turned off at breaker not the RCD or mains. Checked that socket was dead got these readings Line to Neutral 0 volts , live earth 30 volts , neutral earth 30 volts. This is an old French house on a 3 phase supply Split at consumer unit and then each...
Typically the EICR I fitted in this afternoon because I'd hoped it would be fairly simple (new build home, 2007), turned out to be the only recent one that's thrown up a major FI.
Downstairs lighting circuit, 1mm T&E, currently on a 6A MCB
R1+R2 fine, insulation test L&N -> E an immediate...
Hi
What’s the principle .
with a neutral not connected to the neutral bar will be 230v basically a line.
But when neutral is connected to neutral bar there is 0v.
Neutral and earth are connected further on with the same potential but I still don’t understand how the neutral bar and even the...
It appears a sparks has connected the live of one lighting circuit cable to the neutral of an adjacent cable using a cable connector in order to obtain a power supply? The circuit has worked fine for 2 or 3 years but has now failed.
While the cable triggers the NCV there is no current or...
Hey holly electricians, I am asking are live and neutral wires different in composition or same but just some different colors of insulation. Was one type of wire just designed to carry electricity and the other to be a neutral one.? Are they different in composition? For testing purposes if I...
TT system, Zs on socket circuit is 77.2 down a good bit after I added a second earth rod.
When I short neutral to earth RCD doesn't trip.
Can anyone help me out and explain please.
Hi all,
I was reading about what can happen if the neutral on a PME system is lost at some point before the cutout and I have a few questions that I'm hoping someone could help me with.
1) Am I correct in thinking that for a properly earthed and bonded system, if the neutral is disconnected...
Hi, first post here!
Just wondering on your thoughts on RCBO neutral fly leads being connected to the bottom of a main switch?
Went to replace a cracked double pole switch for the storage heater, went to give it a quick test and came across this. Dual RCD board with an extra main switch added...
Hi there.
I’m trying to put a new ceiling light in that’s from IKEA but it has a blue wire and a white wire. How do I know which is live and which is neutral please?
Also can I check that I am going to do this correctly. The current ceiling rose has like maybe 6 wires all connected to a black...
Refreshing my knowledge on circuits for an electric project & would appreciate if you can let me know if my understanding as I will explain/show below is correct.
Figure 1 shows a wire containing a live (red) & neutral (red) (similar to Romex NMB w/out ground shown) and Each bulb A-D are...
Learning and curious
At my home the neutral and earth are joined by the cut out fuse.
The neutral goes up to the meter and the earth goes straight to the board.
I can't wrap my head around how the earth and neutral are different?
When the cut out fuse is out ( some one broke the seal along...
Hi, I need to refit a timed extract fan, there are three connections on the fan body, clearly marked, fine with that, but the supply cable from the ceiling is one cable only, one brown and one blue, the bare earth wire was just bent out of the way. It was working fine before disconnection. There...
Hi,
I am struggling to understand one concept if anyone could shed some light.
as TNCS has combined neutral and Cpc so if on the consumer side hypothetically if you check continuity on N+Cpc without disconnecting any conductor, do we get continuity of Neutral and CPC as on the supply side, its...
I have basic experience installing switches, dimmers, outlets in my home; I am not an electrician.
My brother recently had a light that was not working and asked me to take a look. I have a basic question about this:
When I connected the hot wire and neutral to the light fixture wiring: the...
