I've just picked one of these up on a famous auction site. The voltages, low and high resistance ranges all appear to be working fine but it's not calibrated. I know it's getting on a bit (16th Edition!), but it's fine for learning with at the price I paid for it.
My confusion is in which test...
Hi all. I recently failed a section of my AM2E assessment. Passed 7/10 but failed on some silly things I'm confident of correcting second time round.
One thing that's got me is the 'Inspection & Testing' section. I failed every circuit with the following feedback

Hi, I need some advice on the wiring for a new ceiling light. I have taken down the original light, and I'm left with the wiring in the image ceiling_wiring_01.jpg. There are three cables coming off a connector block in the ceiling, each with a live and neutral and a single earth wire on its...
I am a complete novice when it comes to electrics but I have recently bought a grounding mat and so I've been doing some measurements and I'm totally confused by something.
Upstairs I get a reading from my body of 5 (ish) volts (bare foot). When I touch the earthing mat this goes down to 0.2...
Hello,
Thank you for time, firstly.
I am installing an LED bedroom light to the ceiling replacing an existing old light / fan.
The terminal box that the LED light comes with has 2 openings for me to screw in the wires to. Wires attached to this are blue and brown / black.
The mains (coming...
Hi all,
I replaced my old Electrolux oven which operated with a 13 amp plug.
The new Kenwood oven I ordered says a 16 amp (Requires hardwiring to a dedicated circuit) is required (see pictures below). Is it not possible if I just buy a 13 amp plug and do the wiring in the terminal box at the...
Ever since I was little, I've wanted to be an electrician. Today, I want the same thing, but I've made some educational moves that might be counterproductive to the field. Let me explain:
I am a US Navy Veteran. I was an aviation electronics technician. The thing is my stint lasted one year due...
A builder friend calls me up to have a look at a "strange situation".
He points at a joint box above and outside a back door. "Old outside light?" I ask.
He's extended this into a new conservatory. "That's probably switched" I guess. "No I found a permanent live" he said.
He's run it into a...
Hi,
I'm a self-build amateur - I'll be running cables and getting system sign-off/inspection by certified competent person, and am just working through circuit design basics.
I'm referring to Scaddan's 'Electric Wiring for Domestic Installers' (16th ed for 18th ed IET), which includes example...
Hi all and please forgive me if this has been asked many times before,
I'm trying to purchase and get installed by one of the national electrical appliances retailers a single oven but I'm getting slightly confused as to what they are wanting to charge me for?
So here my supply, 32amp from...
How to connect a ptc heater to a controller, so...
the controller actually turns the heater ON and OFF when it reaches the desired temperature?
I need to keep stable 30 deg temp, but there is no relay switch on the heater (I think that's how it is called), so if the heater is connected directly...
Following on from another thread I have some more pictures and some more information. There are 2 questions in bold.
The customer has bought the avant rapid charger 400V/16A (moder number A426117), this is to charge the Avant Electric compact wheel loader, model e6.
The charger looks like it...
Hi,
I'm an industrial spark and taking my 2391 next week (wish me luck, I need it).
I decided to get a bit of practice and started an inspection on my own house.
I got as far as, b32 socket (ring?!) breaker looks slightly browned, better check it.
3 cables in the breaker two identical and...
Hi
I have had three electricians quote to wire my new kitchen which is currently a shell. The thing I don't understand is that they
seem to differ in their approach to the electrical rules, for instance, two are happy to place oven and hob isolation switches in a cupboard and one will not. One...
Sorry this question may sound silly, but I really don't know anything about electricity so I'm just asking to make sure.
So, recently I bought a machine from the U.S via Amazon. In the instructions of the Amazon page, it said to plug the machine into a 110V socket, but our countries run on a...
Running some calcs I'm confused about what Zs to use when calculating 5 second disconnection times.
In circuits with 1.5mm2-4mm2 cable a fault doesn't seem to pull the voltage down much at the trafo terminals so from an ohms law perspective the current magnitude reflects simple V/(R1 + R2)=I...
I wanted to relocated three separate switches into one 3 gang location, and replace the switches at the same time. Unwisely, I did not take pictures or make a sketch of the wires going to each switch. Now I am confused about how to wire the new switches. The first switch controls both a whole...
