23:41 oooh, you missed one 😱 luv the idea of drilling out the back and using the wiska grommets. always thought they were missing a trick by not doing a rectangular plate that would fit the knockouts on the boards, and have the fire proof stretchy bits on it that would let you pass the cables through. also, with liability being an issue, the idea of using those 'void if removed' things is growing on me too.

Crabtree device is a voltage operated earth leakage circuit breaker with in and out on the earth and a sense resistor in between. The problem with them was any parallel earth paths on the electrical installation they didn’t operate. Main bonding had to be on the input side and not connected to the c.u. Also that’s why sometimes you come across showers immersion heaters boilers etc with the earth not connected. Excellent videos thanks.

Very good video and nice neat job. Shame you didn’t have several IR neutral to earth issues as I’ve come across on a recent job, id be interested to see an optimal approach to finding the parts of the circuits causing the issue especially as the elderly clients don’t want me to cut open any walls and are not happy for me to move furniture and lift floorboards. I started doing an EICR but came across so many issues with broken rings, incorrect polarity no earth sleepving or grommets etc etc I just started to fix as I went along. They may decide not to have a new board should I say I need to rewire with new cable so will be left with an old 4 way yamex CSU with no RCD protection and signs of overheating on the ring that has all the houses 30 sockets on it. Any advice based on similar experiences would be most appreciated.

Hi Chris what hole cutter did you use for when you have cut them holes in back of c.u and put the grommets in. Was is a step out bit or an actual hole saw

Question : had 2 electricians doing different things so a bit confused foe 18th edition consumer box change do we need smoke alarms aswell to be connected ?

Old Voltage Operated Earth Leakage circuit breaker. The main earth would be taken to one terminal, and the earth rod connected to the other. The trip coil was between the two terminals (labelled E and F). if an earth fault caused the voltage between the two terminals to go over 50 volts the coil would trip the mechanism and disconnect. As others have commented, they have not been recognised as compliant fault protection since a Long time back, but at least it gave a free double pole isolator to make everything dead for the board change.

Good bit of work mate 👍🏻👍🏻👍🏻

Interesting , I can see that you are "just a lad" 😂 The breaker you referred to on the left is Voltage Operated ELCB, I have installed them in Ireland some 50 years ago, it was the latest technology ! They did the job but has at least one" big" fault, if you don't know look John Ward's excellent videos on them. As for the PME terminals if you test you may find there is no connection to it from the supply !

Nice job apart from wading through the cupboard contents to get decent access. Any reason why you didn't bring the existing earth cables down the back of the mounting board?. Looks odd.... Yes I know the two main cables run on the front.

Pablo, the man, the myth, the myth, the myth, the myth...

How did you exactly disconnect from the mains supply? Were the wires hanging off live when you disconnected them from the meter going into the smaller crabtree RCD??

You missed the left hand screw on breaker no.5 @ 23.40 :D

I was a spark many years ago, I know my stuff. I’m quite capable of fitting a new CU. How do I get certification?

Those switch covers at 26:08 with edges covered by the vertical architraves -- use a vibrating saw cutter and cut through the covers by the edge of the architraves. Switch covers can them be removed normally (without the cut-off edges).

I dont know if it's possible the the FUSEBox consumer unit as I haven't seen one and I couldnt tell with the video but other manufacturers have square knockouts on the back with fire resistant blanks to fit in to buy separately where the cables could push through instead of drilling, depends which is easier on site. Maybe fusebox have something similar

I started out as a EE and did a lot of hands on industrial work before transtioning into software engineering. Over the past several decades I've worked on a lot of residential stuff in Chicago where we have strict codes requiring EMT. As always, if I run into a situation for which I have questions, I've got friends who are certified sparkys. A big problem I always run into on the old places here are the layers of fuckery people have done. My industrial experience has proven invaluable over the years. Something about having giant and expensive machinery with 480 3ph that hones one's focus and discipline to work clean and proper.

The Crabtree device is a VOELCB, voltage operated electronic circuit breaker. When switched on, an internal coil adds around 100Ohm impedance to the earth, electromagnetically actuating the switch to trip off in the event of a voltage becoming present on the earth. This protects against shorts to the earth conductor, but does not protect against shorts through a person to terra. The device does not detect an imbalance in load between L and N conductors like an RCD.

Looks neater too if they line up with the devices. P.S. those switches that can't be removed, I've seen examples of that in new builds too. Gone round putting fancy new switches and sockets on then come to that and got one trapped between a doorframe and the corner with another doorframe completely blocking one of the screws. Would it have killed them to use an architrave switch?
