Hello everyone! I'm back once again after a brief hiatus. I am trying to set up a CCTV recording system for a person who is not much into technology and doesn't have much knowledge of things like these. Actually, I am a tenant in his paying guest facility. I have already installed one indoor...

I was trying to post a thread in the Programming section, when I started receiving error dialogs when I clicked on "Post Thread". The console shows this: <div class="cf-section cf-wrapper"> <div class="cf-columns two"> <div class="cf-column"> <h2...

Ok, so is the chart wrong? Because the wires are copper wires, but you are saying that the ampacity is for aluminium conductors.

The issue was the hall bathroom line got its phase/live from the ##4~\mathrm{mm}^2## wire, but its neutral was connected to the ##6~\mathrm{mm}^2## wire because it was directly connected with the neutral from all the other rooms. So when the isolator was switched off, the neutral was cut off...

Thanks for the ping, @gmax137. In India, we have three major "boards" of education; two central boards — Central Board of Secondary Education (CBSE) and Council for Indian School Certificate Examinations (CISCE), out of which the former is directly under the control of the central Govt. And...

Yep, got it. Will do measurements and post in a new thread; it'll be quite some months before we buy it if we do. The A/C is rated 1.5kW at 230V, so just 6.5A. At 170V (that's the lowest I have seen here), it'll be ~ 9A. I'll take more readings though at full usage.

Yeah, it's an autotransformer. They are called servo stabilizers here, not sure if that is standard terminology internationally. I was planning to buy one for the big loads like the air conditioner, microwave oven and the refrigerator (for example). How will this exert additional load on the...

This setup has resolved the problem for now: We have planned a few enhancements, but that will be in a few months. Also, two 10kVA servo stabilizers seem to be a better idea than one 15kVA. Will cost a bit more, but mixing wires of different gauges is not an option, obviously. If each 10kVA...

I was wondering if I could add a 15kVA servo stabilizer for the entire house. Even though I live in a metropolitan city, we do have sudden voltage fluctuations, as well as constant low voltage in the summer due to every house running an air conditioner. Part of this happens because people use...

None that I know of, to be exact. It's customary to keep the house circuits (includes lights, fans and 6A outlets) on a DP isolator before passing into separate SP MCBs for each room. Larger loads like air conditioners and microwaves are directly powered via an SP MCB from the main MCB.

From what it seems (I tested yesterday a bit), the air conditioner and the treadmill outlets both have their live and neutral wires directly connected to the pair of 4mm2 wires. The bathroom and geyser section is the only one that is connected to the 4mm2 live, but uses the existing house wires...

Abridged by me Yeah, I know. The entire circuit is full of violations. None of the 25A or 16A rated circuits will ever be able to carry their full capacity. Fixing all the violations requires two things: money, to buy good quality higher capacity wires, and an electrician who will listen to...

Need some help in understanding the current ratings of wires. I had asked about this in another thread, and learnt that power ratings of wires depend on numerous factors. To simplify things for me, I could successfully dig out the product datasheet from one of the notable companies in my country...

Yes, true. We are going to re-wire things.

The incandescent bulb blinked only once. It never lit up after that one time, irrespective of whatever combination I set the MCBs in during further testing.
