Hello,
In our country, electricity/power is cut /outage without prior notice for 2 hours a day.
Does the sudden shutdown of the electrical appliance(such as mini-split inverter AC, refrigerator with and without inverter, TV..) damage them?
Does the problem come from when the power went out...

BG are stating that these are 18th edition compliant. I'm doubtful if they meet regulations 536.4.3.2 & 536.4.202 - overload protection of switches and RCCBs.
the RCDs are rated at 63A. There is no way of configuring the supplied MCBs that...
See this time after time - poor installation:
new split load board on a re-wire tt installation. The main switch is not a time delay rcd. The board is metal and there are split load single insulated conductors before the 30mA rcd's.
If these conductors touch the metal work the board may...
I am a retired electrician and I've been out of the game for a while. My son asked me a question the other day and I wasn't too sure how to answer it so thought you lot might.
He wants to use rails to supply 5 modules, each module will have 40 small actuators that operate at 24VDC at 0.9As...
Dear All,
I was called to a villa following a fire incident had happened. the Indoor AC, wall mounted split unit was partially melted and had caused fire in the room over night.
the indoor unit was fed through the outdoor unit and not a separate socket. The outdoor unit feeder on the DB has MCB...
I have a client with what appears to be an intermitent fault on the lighting, but trips the power.
The installation has a 16th edition board with sockets on the RCD side, and lighting on the other side as usual.
Occasionally when the landing light is switched the RCD trips on the socket side...
Our house has one external feed going outside to power lights.
We've recently renovated our garden/drive etc and now there are three different zones where we would like to have lights and control when they are on/off.
With one source going outside and one switch, I was wondering if there is...
Hello friends Myself Arif Patel and I am an Electrical engineer from Dubai. preston, UK.. I just wanted to Know, I've been asked to complete an electrical load list with the watts required for each phase of a 3Ph, 400A, 11kW VFD. The VFD is feeding two motors with a total load of 21A. How many...
What are smallest in physical size split core current transformers. Max load 100amp max cable core size 35mm.
Power cannot be isolated and space at a premium.
Thanks Andy
Hi - first-time post from a complete novice.
I want to install a 24kw electric boiler on my property but that size requires Phase 3 supply. Northern Powergrid don't install Phase 3 in my area (off grid) but can increase capacity via a split supply. Can I run a phase 3 boiler from a split...
Did an EICR that passed 5 years ago
Several things in the picture raised concerns for me.
Comments please - photo at end
First photo shows a split concentric in use AFTER the meter, the supply is a TNC-S supply and the split concentric has the following items
Single insulated neutral...

Hi there.
I am a doing some DIY kitchen work. In Ontario Canada, code allows either a split 15 amp multi-wire circuit or a 20 amp circuit (each with two receptacles allowed on the circuit). We only need GFCI if 1.5 m from a sink, so the outlets I am installing do not need GFCI protection.
Is...
Hey all.
New here and new to 3 phase.
I had some electric experience on set in Los Angeles as a gaffer for a couple of years, but it was mainly single-phase - counting amps and avoiding blowing circuits type deal. Also did basic wiring in my old 73 chevy truck as well. So nothing huge.
But...
OSG Pg.40 says:
'[Split CU with 2x RCCBs] is not suitable for an installation forming part of a TT system as there is insufficient fault protection of the single-insulated conductors that connect the load side of the double-pole main switch to the supply-side of the RCCB's.'
Why is there...
Now we used to see a lot of this when we did new build flats etc
But I think this domestic sparks is the first one on Youtube that I have seen use Split Con cable on a house board change
Hi we have a split phase supply and had a EDMI ES-30B 3 phase meter fitted.
Our readings are extraordinarily high. It is an old farmhouse but there is just myself and my wife and we are using 29,565 kWh per year. 81 kWh per day. We just have an electric shower, electric cooker, appliance like...
