    UK RCD vs MCB trip

    don't worry, it would blow the guts out of the micromave before tripping your breaker with 160 amps. You might want to reassess your breaker ratings.

    UK DIY. Can anyone help me understand why this complex arrangements of wires are connected this way from these two seperate meters

    it has an earth. The last wire on the right goes back to the large two screw connector. If they are going to use it as an earth bar they need a bigger earth wire back to the connector.

    UK RCD vs MCB trip

    because a RCD reacts faster than a breaker. I said that in my very first post. You can't say for sure that if there wasn't a RCD that the breaker wouldn't trip.

    It definitely needs someone to look at it, but I don't think it is as bad as people are making out. That earth bar (furtherest away) needs two screws holding the wires down. A door on the whole cabinet would make a nice touch.

    I will get to his other posts, but I just want to correct him on this subject first, Boss.

    UK RCD vs MCB trip

    Apparently not. Throw a hairdryer in the bathtub and see how conductive it is. When did DC come in to it? you can't change the story to suit your theory. You have a nice way with words.... the only one you left out was "gently massage" :D Facts don't work on something being unlikely, but...

    UK RCD vs MCB trip

    Hold on a minute, are you trying to tell me that you wont get a dead short from water? and it doesn't have to be 48 amps, as the circuit itself would already have a load on it that is at near full capacity. What do you think we relied on before RCD's? You crazy UK leco's should brush up on both...

    UK RCD vs MCB trip

    I would still expect the RCD to trip first

    UK RCD vs MCB trip

    NO, A MCB will trip with an earth fault, but not when it is also protected by a RCD as the RCD trips too fast.

    UK RCD vs MCB trip

    Woah, not so fast my friend. There is water involved, so there is going to be an earth fault. The reason the RCD trips first is because it is designed to trip within 40ms of a fault occurring.... way faster than any breaker or fuse will ever respond.

    Twin and earth in pipe...

    Even thou it is only a garage, it still looks terrible. What if the owner eventually turns it into a man cave or something similar. Doing an amateurish job and trying to convince everyone via youtube that you are doing the job of a professional is just being a snakeoil salesman.

    Twin and earth in pipe...

    Regardless of the insulation, the cable should have been run before the sheets were nailed on. Any qualified electrician that has pride in his work and likes to see the job done right, would never run all that conduit when the finished job is easier, quicker and looks so much better by hiding...

    UK Lighting connections help please

    You are over thinking this. The rest of the house works, the problem is in the two way switches. The bottom 2 way needs the "normally open" terminal swapped with the "common". that will get power to the top switch with both "on" or "off" selected. You might have to do the same with the top...

    Twin and earth in pipe...

    Let's be serious. There are perfectly good wall cavities there, why would you use any conduit at all? Conduit doesn't only look terrible, it is going to derate the cable. Be professional and put the cables where they belong.... out of sight.

    Storage heater tripping

    Power it up and test across the element, if you have power to the element then the element is blown. you only have an element and a thermostat.

    External Power

    What is this black magic that you speak of? 2.5 mm protected by a 40 amp breaker? the cable will melt before the breaker trips. If the basement supply cable is large enough, make a mini sub board where it enters the basement and have a circuit for basement outlets and one for the garage. Run a...

    Just work it out on your full load current of 52 amps

    Twin and earth in pipe...

    That is without doubt the ugliest wiring job I have ever seen. What is going to happen when you want to put a bench along one of those walls? you are going to have a 20mm gap between the bench and the wall. Most of the outlets are up high, the logical and neatest way would be to go over the top...

    even thou the fan will work fine the way it is connected, you paid him to fit a timer fan. whether the job is easy or hard shouldn't come in to it. Get him back to install the timer.
