    Extraneous conductive part test

    Hi all, im aware of the test needed to be done when trying to find out if a metallic object is an extraneous conductive part but for example, if you had a copper water supply system in a house that is fed with a plastic incomer pipe out the ground you will always receive a low resistance reading...

    Anybody used conductive paint?

    After my recent, first foray into LED strips, I now find myself needing to repair a pcb where a copper contact has come adrift from what appears to be a carbon "pad". I found this: https://www.pcb-soldering.co.uk/bare-conductive-electric-paint-soldering-glue-10ml-pen Any advice greatly appreciated!

    UK Bonding of extraneous conductive frame

    TNC-S main supply with 16mm swa supplying garage consumer unit from main consumer unit in house, then 4mm swa supplying pond equipment through pond fuse box. (Pond cable run approx 40m) Pond has a metal unistrutt frame and cover over pond equipment, this frame has its support legs concreted...

    Extranous conductive parts

    During an EICR I have come across a metal tap and copper pipes supplied by a blue plastic pipe. This measures 0.022 MegOhms, this is directly under the consumer unit which is metal. Is this an extranous conductive part?

    Extranous conductive parts or exposed

    During an EICR I have found an isolator with no cpc present bolted to a large metal post and all the motorized metal car park gate, the fact that the isolator has been moved but the cpcs are not present. I get a zs from the metalwork of 36 ohms, as the wires pass though I class this as exposed...

    Metal Bed Frame - Exposed Conductive Part or Not

    So to try & keep confidentiality, a broad question without specifics; A manufactured bed, mechanically operated by electrically powered motors. The metal bed frame would raise and lower the bed, and also be able to raise/lower the head of the bed and the foot of the bed. Would the metal bed...

    Is the MET an exposed conductive part?

    Hi all, while working on the bonding task of the L2 G&G I assumed the supplementary bonding CPC should be 4mm2 due to the table in the OSG -(p.51. size of protective conductor = 16mm2) However another student said the MET is an exposed conductive part so the CPC should be 6mm2 - even though...

    How Conductive Are The Metals Used To Make Electrical Fittings?

    I'm just studying electrical conductivity and struggling to find out which metals are used in sockets/plugs/switches and the main fuse etc. I always thought these were brass, but I'm not so certain after reading the link below. Would they use the most conductive metals available, and could...

    Old MICC cable underground to garage, extraneous conductive parts

    Ok so the scenario is there is an old MICC or pyro 1.5mm 2 core cable supplying the garage run underground on a 16A circuit breaker that is RCD protected. In the garage there is a water pipe fed from the house, at the house it is bonded using 10mm, at the garage bonded with 6mm. I think the...

    conductive soil

    As the electric board installation people are being very unhelpful we will have to stick an earth rod in some reclaimed land on a harbour edge. We are not expecting to find this easy and we have been considering digging a hole, infilling it with that conductive soil stuff you can get and putting...

    Testing extraneous conductive part

    Just been read through this and it says: How to determine if it’s an extraneous-conductive-part For this, a simple measurement is undertaken. This is done by testing the resistance between the suspected extraneous-conductive-part and the MET or the nearest known connection to Earth, such as...

    Bonding Extraneous Conductive Parts

    hi. Question re bonding a metal where cold comes in as metal pipe ground into house. So cold will be bonded where service comes in. Read article in wiring matters 2019 about changes for part 18. Example given of faulty kettle where fault to earth exists at kettle, some one touches kettle...

    Extraneous conductive bits & pieces

    metallic portacabin used for offices,Swa is on a steel caternary,enters office to Rcd DB. No separation of swa earth Tncs @ cabin. I want to Tt it,what’s your thinking of caternary wire,it comes from building to cabin. Will this still import Tncs,& will it also need isolation from cabin,where...

    Earth fault - potential on exposed conductive part

    As can be seen from my profile I am not a qualified electrician but I'm studying in my own time just for the sake of it. I understand the principals of earthing and bonding but in this video by GSH Electrical.... .....at 2:10 minutes in he says exposed conductive parts under earth fault...

    Removal of extraneous conductive part

    within a building supplied my a PME system it’s not possible to main bond the extraneous conductive parts effectively back to the origin. Resolution instead of changing to a TT system remove the extraneous conductive parts. Water pipe: this comes out the ground so change this to plastic and...

    Extraneous conductive parts

    Morning, so just finishing off the install to a shepard hut which is located in a field. The construction is steel chassis, plyboard floor, timber stud clad with corrugated sheets. The corrugated iron sheets which clad the unit are plastic coated and there is no continuity between each sheet...

    Extraneous conductive parts

    Hi all. Looking for opinions on here. I’ve identified during an eicr that a dry rise pipe used for firefighters in the building is in fact an extraneous conductive part and that it is not bonded back to the MET. However what I’m questioning is it’s accessability to be touched in the event of a...

    Extraneous conductive part as bonding conductor

    Been nosying about at my brother's new house this week and fixing a few bits and bobs. The electrical installation mainly dates back to the early 80's at a guess and apart from a few broken accessories and a lack of RCD protection (now fixed) it has all checked out okay. PME earthing. Today...

    Tv - 75v exposed conductive parts

    mother inlaw says - I keep getting a shock of the back of the tv when I try and move it to turn the plug off. It’s a wall mounted tv in the kitchen. I thought initially it must be just static but told her I’d have a look. As it happens, every screw, or exposed conductive part on the tv is...
