Consultation on the power scheme of a private house
2. What is the best way to conduct wiring for lighting, as in the diagram, or for lighting not to use an RCD? Grounding is only planned so far, I will lay the wiring with a 3-wire cable ...
3. I picked up the protective devices for collecting the shield, with the next message I will attach the file, I would like to know if I picked them up correctly taking into account the circuit?
1. Well, as I understand it, one of the machines is in the shield with a counter and the other is in the utility unit and is powered from the first, remind me, or is the metering board generally separate? In general, put at least electrical panels in every room, if only you would remember that if the GENERAL input machine (which is near the meter and from which everything you have is powered) is 40A, then you cannot physically switch on two 40A shields physically power SIMULTANEOUSLY.
2. Regarding the RCD for lighting, we recently published a new article, you can read it here:https://our.electricianexp.com/en/uzo-na-osveshhenie-po-pue.html
3. Well, a circuit is needed here.
Hello. The power allocated to the house (5.5 kW) has become known - here is a diagram with input automatic machines of 25A each (in the panel of the house, and in the panel of the hoeblock).
1. Is the RCD (1-2-3-4-5) ON 25A selected correctly in the circuit?
While my message is on moderation, I can’t send the following message ... ..
Or this scheme will be more correct
To be honest, I can’t see the difference between the two schemes. Everything on it is logical and normal. The only thing that can be advised is to install an introductory machine or differential in the hosblock, so that it would be convenient to turn off everything all at once, you never know what! And even for “wet” rooms, a bath, for example, it is better to put an RCD of 10 mA, and if there are false alarms, then replace it with 30 mA.
By the way, it seems that you and I were wondering such a power (5.5 kW 25A) then!
I don’t understand anything, authorization is required when sending a message ...?
What kind of power supply is needed in cross section for an LED lamp?
Hello! Do you want to know about the cross section of the wire? Usually LED lamps consume little power, so 0.75 mm² wire is suitable, but in general if it is a stationary lamp, lay 1.5 mm² (because it is more durable), and if it’s a type of table lamp - 0.75 mm²
Hello.
In the first diagram, 25A introductory machines are located in both panels.
In the second diagram, the second shield (the shield of the hozblok) is powered from the input machine
25 A of the first shield (shield of the house)
What is the best way to power the second shield (the shield of the hozblok)?
Thank.
In principle, it is the same, but the presence of an “introductory” machine in the electrical panel of the hosblock will allow to quickly disconnect everything that is powered from it in case of anything.
