Looking for someone to help with this dilemma. Image attached to try and explain it better.

I need to design an electrical panel, and the main circuit breaker is rated at 250 A. We are implementing a 100% Brum solution for the panel, but Brum's earth and neutral busbars are rated up to 125 A. If I require 20 earth poles, can I use two 10-pole busbars rated at 125 A each? Or does each...
I used a Contactor instead of an ATS to connect 2 power sources (main and ups) for power redundancy and the output is connect to a Dell server. i.e, if main power is lost contactor will changeover to ups power and there should be continuous power supply for the dell server…

Not quite as daft as it sounds, this follows from my thread a day ago. I need to find an electrical (ideally, gas could also be an option...) to heat a plastic bath tub of water to around 45C, and then maintain it. I've rejected the idea of using those deathtrap looking immersible elements...
Hello everyone,
I have a goldsmith oven to which I had to change an SSR relay because when it reached 475 degrees centigrade the temperature increase stopped. Since the oven must reach 800 degrees in about two hours, I have to solve the problem.
I changed all the main components to the oven...

Hi
I am trying to create a thermal cutout circuit to protect a large (10sqm) silicone heat pad table. The total heat pad load is around 30A (split between seven 1kW heat pads), running off a single phase 32A supply. The heaters are controlled with Eurotherms and SSRs, which fail in the closed...

How many threads have there not been regarding the issues resulting from employing a TNC-S supply system? The current earthing arrangements to mitigate the consequences of a broken DNO neutral are not satisfactory and are not likely to change in the foreseeable future largely due to cost. But...

I'm moving my workshop into a room that contains the intake. I want to put cabinets where the switchgear is at the moment, so it would be very handy if I could condense it into a small space above the meter board and put a little cupboard around it. I am looking for the most compact...
Hi All,
Sorry to jump straight in with a question but not sure where to start. I’m basically looking for a portable solar option around 100W to cover all bases:
