Hi all
I was in need of some 2.5mm twin and earth for a spur, was passing tool station and called in.
Got Twin & Earth Cable (6242Y) Grey 2.5mm2 x 25m -
But when looking at the cable its got written on it: 2.5mm + 1.5mm.
So it looks like the live and neutral is 2.5mm but the earth is 1.5mm...
Hi,
A quick question, maybe a stupid one .... but it baffles me ,and I cannot find any info on the net. If you do the continuity test on a lighting circuit to get your resistance values, wired in twin and earth, how do you the the value for the earth ? Obviously you link the earth and phase or...
In "Advanced Electrical Installation Work" by Trevor Linsley, he says that an earth electrode rod that is 1m deep will typically have a resistance of between 10 and 200 ohms. Given that fault currents can supposedly, momentarily, be in the order of 1000's of amps, this makes me scratch my head...
Ime sure most of you see this on a day to day basis but as I dont do house bashing this still annoys and baffles me....
What is it with DIY'ers and the general lack of care when it comes to earth wires?
Went to change one of my lights this evening, Changed a few sockets and switches but not...
Hi All,
I am fitting a new kitchen in my second floor flat (I am not doing anything electrical myself apart from the most simple stuff). I pulled the old kitchen out several months ago and attached to the kitchen taps were earth cables which I removed.
I have called an electrician to fit new...
Hi,
I need to put a new socket on a wall in my living room, it will spur off and existing socket and it is my closest option (nothing upstairs either), the thing is there is a door way in the way. Instead of going up and over the door am I ok to channel a small path in my concrete floor and...
My name is Maciej Marosz I'm inventor and Engineer (about me MAROSZ 's PATENTS) . Below My link to forum ( physics ) I'm looking people who want to start research this area it can reduce in future energy transport cost / it also can be new electric methode to evaluate speed ( airplane /...
Hello all,
I have just done a pre-works visit for a CU change and found continuity between neutral and earth!!
This is a TT so I didn't think I needed to disconnect the main earth but after getting continuity between N-E I did, I also disconnected main bonding but still getting N-E continuity...
I was carrying out an r1+r2 today and when disconnecting the cpc out of the earth bar to link worth the line it sparked on removal from the earth bar....
I tested between the cpc and the earth bar and got 120v
Tncs earthing arrangement
I've carried out insulation resistance test and that was...
Doing an EICR. the house has loads of down lights. To test propely do i need to remove each down light and access the earth in a connector block. Assuming there class 2 fittings.
Customers not that keen on me removing them from newly decorated ceilings.
Also the customer doesnt want me to...
Please don't lambast me over this question!!! Some time ago there was controversy over the simple plug in socket testers on their unreliability due to the non -detection of a neutral and earth reversal.Obviously a figure of eight test would pick this failure up.I remember old multi function...
Is there a regulation against running twin and earth cables outdoors, clipped direct within reach without mechanical protection or is it just a good practice thing ? Not got a regs book to hand, can someone give me the reg no if there is....thanks alot
Say for instance along fence panels at...
Hi guys.
Is it ok to spur off a old socket that's wired in the old twin/earth cable its either tinned copper (conductors and earth is sranded) or aliminium as iv heard metals can react with one another.thanks
I have come to a site to assist the install if fire protection equipment. Another contractor is doing the main electrical wiring. Working with one of them I observed him joining a 2.5 T&E ring cable under floorboards. I expected him to use a new style maintenance free joint box (e.g. the Ashley...
Hi there,another question from me,I have a 10mm radial for oven&hob,so doing IR test It shows me 0.22 between neutral and earth,so I went to investigation what could cause a problem,there is a 60amp JB for that circuit above the hanging cupboards in the kitchen,so first thing I did,disconnected...
