Hello community, I need some advice from you… My father (an electrician) replaced all the wiring in my apartment, including the fuse box. The problem is, he didn't write down the wiring for the night storage heater… The wiring for the control system is connected, but he didn't unplug it at all, only the wires…
Hello everyone, I'm an electronics engineer and would like to spruce up my sub-distribution board, as it's located in a visible area of ββmy house. My idea is to replace the standard cover with a transparent panel and also install subtle lighting to make the whole thing more visually appealing. Of course, I want to…
Hello, when and by whom should a house connection box be replaced?
Hello, first of all: I'm not a certified electrician, but I'm confident in my statements. This post does not constitute professional advice and should therefore not be relied upon as a guide or as a basis for practical applications. π π²πΆπ» π£πΏπΌπ―πΉπ²πΊ: After gradually redoing some things (light switches/sockets) in my house (built in 1978, ππ²πΆπππ»π΄π²π»:…
Hello, my Qsc power amplifier has a very high inrush current and therefore always blows the fuse. What can I do about this without installing a new sub-distribution board?
If I want to isolate a socket via a contactor with a switch, how do I connect the socket? Do I then need to connect the circuit breaker (CB) from the socket and then from the CB to the contactor, or vice versa? And where on the contactor do I install the normal switch that…
Hello, I found this push-button relay in a house and plan to replace it with a Shelly because it is causing problems (it no longer switches properly, sometimes even short circuits). Can anyone tell me approximately how old this relay is?
Situation as follows: 40A Fi in the sub-distribution B16 LS in the sub-distribution to the room in the basement From there, it continues into the garden shed. Would it be selective if I installed a B10 circuit breaker in front of the garden shed (still in the basement)? Would that actually help, or is a…
Good day, I have a problem with this distribution. When the sockets in 3 rooms are loaded, the main RCD trips. In the bedroom, only the socket under the light switch triggers the RCD, the others that are bridged across the socket do not. In the bathroom, the main FI and the RCBO trip regardless…
Hello, I have a question regarding the fuse in front of the sub-distribution board. Can it be smaller than the main switch and the overcurrent protection on the sub-distribution board? E.g. fuse in the HV 32A and in the UV the main switch and overvoltage protection 80A?
Hello, in our house (a block of flats with 12 apartments) I found an RCD labeled "Gutter" in the meter cabinet in the basement next to the circuit breakers (for the individual circuits in the basement compartments) and other RCDs. Now my question: What is this good for? Gutter heating or something like that?
Hello everyone. First of all, I am an electrician myself but would just like to hear another opinion. Normally I always run a 5x10mmΒ² or 5x16mmΒ² (depending on the case) cable from the meter to the sub-distribution board(s). Now I spoke to an older electrician and back then they always laid a 4x10mmΒ² and the…
