As the charging point must be outside the DB equipotential zone (separate earthing rod), are people using 2-core SWA for EV points and eathing via the armour?
Hi all,
On a recent job (electrical) the customer asked if I could add them a point to hard wire his computer to his internet. I put him an ethernet socket at each end, ran a piece of cat 5 in between and terminated with punch tool as per a bt socket. Customer reported not being able to get...
New circuits. Ra of 229 Ohms therefore the rcds are for fault protection by design. Zdb of 0.29 (10mm gas bond) so are the rcds classed as additional protection?
I'm considering a career change or trying to implement a 50/50 split between my current work in IT - largely working in a technical capacity as a 3rd line support analyst and re-training to get into the green sector and do part-time work (or potentially a full career change) either fitting PV...
Hello,
I need to add a switch for an outside light. The obvious place is near the back door but that is where the fire call point will go.
Is there a minimum distance in any regualtions between the two?
E.g. to prevent someone from accidentally pressing the call point while trying to press...
I've been working for a firm for a number of years now with jobs on the side, recently gone full time solo. Everything I've done up until now has been either day rate, or price work.
I'm based in Surrey / Middlesex by the way, most of my work is in the areas surrounding Heathrow airport and...
Good morning fellow electricians. Now, as I am sure you have all been enjoying, I have not been on here much lately, as I am jacking in very shortly, or at least not renewing my scam membership. So, with only 20 days left, it has just occurred to me it might be a good idea to install myself a...
Hi, I just have a few questions in regards to testing an RCBO circuit
Is there a requirement to test at either the furthest point or the DB or is it down to the testers discretion.
Do the test results differ?
What tests on a circuit will trip the RCBO when you are away from the DB. Is it...
I have a nice job on in a few weeks which includes wiring up a solo chargepoint EV point. The pod doesn’t have its own RCD like Rolec do.
I am rewiring the house and intended to use either a type A RCD or RCBO.
As they also detect small levels of DC leakage.
I use BG consumer units but I...
I am currently doing an EICR in a warehouse and one of the circuits is for a Fork Lift Charging point (32A) In Light of the 18th Edition and all circuits being protected by and RCD, should I recommend that the MCB that is feeding that circuit at present be changed to an RCBO ??
Hi,
I know there are many ways to achieve this. I just wanted to know that the diagram I have drawn for this 2way switch would work. Just having neutrals at each point, for future smart switches. Thanks and merry crimbo
Hi all,
I have been asked to install an EV charging point for a friend who doesnt have an electric vehicle but would like either a cable ran in or a charging point installing to future proof his home.
My local training centre runs a course for EV points and I was wondering if the course is...
We have a door that will be in normal use but is designated as a fire exit, however, there are all glass windows site managers that think they know it all has said "can't it go on the wall some three meters to the left" even if building control accept it I don't think it would comply with the...
With the 18th edition coming out, will this just mean more rules broken? Judging by the number of questions on this forum most electricians struggle with the 17th edition! I assume any installations wired under the 17th edition are now dangerous? Mmm better think about rewiring my stables. Only...
I am looking at section 722 of 18th edition for EV charge points. Section 722.411.4 imposes restrictions on the earthing arrangements for TN systems. For an external chargepoint connected to a domestic PME supply the accepted solution to avoiding the restrictions of 722.411.4.1 seems to be to...
Hi guys, I've never done any aerial installs or an data cabling before so bare with....
I have a customer who lives in a block of flats, she has 1 aerial socket in the lounge but she also wants 1 in her bedroom, directly above the lounge. Am I able to just extend the socket in the lounge by...
Guys, i like to have a broad knowledge base and range of work, as i get bored doing the same things day in day out.
From working on F1 hospitality units, to kitting out warehouses, to a little bit of domestic (however i generally hate domestic Re-wires, so rarely do these).
I have been...
Hi Guys,
A debate at work and im slightly confused and thought maybe someone here may shed some light.
What is the point in doing your 2391 Testing course? Apparently to be NIC Registered you do not need to have 2391 Inspection & Testing & You are able to sign work off.
However if you have...
There seems to be a lot of confusion around at the moment as some engineers are flagging up a non-conformity which i had previously never thought about.
Basically I've been sent to a few jobs where its been recommended that an MCP is put on the exit gate to a loading yard? Yes i suppose this is...
