So I have an issue with a Zappi car charger discharging my home battery when called to charge by the octopus intelligent system. This is happening because the Zappi charger load is measured by the main supply CT so is seen as a home load by the solar/battery system and the battery discharges to...
A strange one in my kitchen.
3 sets of 2-way switched GU10 `Philips down lighters. ( no dimmers)
Have been fine for several years.
Last week the fan/light remote receiver, ( connected via a on/off wall switch, using live which also goes to lights, neutral permanently connected to lighting...
Year 2002 two ton 240vac hvac compressor. Plaque says 21.4 amps. Paperwork says use 30a dbl breaker.
Is that 21.4 amps on each hot wire?
Air handler central hvac 120vac fan paperwork says 6.2 amps
2 fridges in house. Plaques say 6.5 & 4.5a. 120vac.
Both fridges on same hot. The 6.2 amp...

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...
Hello,
Newbie here. Tried to find the answer through searching, apologies if I've missed it.
We are refurbing our house. I want to install RGBW LED lightning.
3 zones: A) Round the lantern roof light, B) Kitchen cabinets and Island C), Snug room (TV and cabinets)
I would like them switched...
I am a retired electrician doing a home rewire.
I'm taking my time because I fell about 3m off a ladder & put both bones through the inside of my right leg.
That has slowed things down a lot...
My understanding of the AS:3000 regs is that all circuits in a domestic residence must be RCD...
I have a bathroom fan with a moisture detector that turns it on and off. It also has a control circuit to turn it on/off when moisture is not connected. This is a no voltage/no current circuit.
I want to add a parallel control circuit that would of course be no load no current that I can turn...
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...
Hello. New member here. Electrical enthusiast.
I am at a friend's house in the Bahamas and decided to look at the load center in the house, which was built in 1999.
The load center is a 1999 Square D QO Cat. No. QOC24UF.
A 2.0 AWG copper conductor is attached to one of two neutral bars (that...
Morning all,
I'm wondering if anyone has much experience with the Tesla Gen 3 Wall Chargers? Quick look through the instructions shows no PEN fault detection; easily dealt with using a Matte or similar. Also, I noticed no facility for Load management/curtailment of the installation via CT...
There are electrical engineers who just mutter the slogan "Safety is the top priority," and simply convey old and inaccurate Cable Tray Weight information to the Architectural/Structural design department without trying to calculate the Cable Weight on the Cable Schedule.
As the result...
My circuit panel has two banks of breakers, each bank protected by an RCD. One of these RCDs has been problematic in that it trips intermitantly. A few months ago it became so frequent that we had the RCD replaced. It would trip regardless of what load breakers were shut or open. No fault could...
I have a L21-30 receptacle. Theoretically speaking, if I want to power a 30A load that requires a L5-30 receptacle, can I just use a L21-30 to L5-30 adapter (PN: IBX-5158-01)?
I am sending power to some 5v led lights about 50ft from the transformer. I was going to use some CAT6 direct Burial cable that I kept after a contractor accidently cut it (I replaced the wire as I did not want to do an underground splice).
So I plan to use 1.5 pairs (three conductors) for Pos...
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...
Went back it a house after they upgraded shower to a 9.8kw, pulling 40a constant.
We had wired it with 10sq and 40a RCBO.
10sq Neutral cable looping from neutral bar to RCDs and on to shower RCBO melted at neutral bar.
That's fair enough, must have been pulling a fair whack through it.
So I...
Hi there, I'm looking for someone to take a look over this load calculation I've done to see if it checks out. I'm using the Optional Method. I'm looking to add an induction cooktop (shown in red) and it seems like it should just fit on my 200A service. The main question I have is if I can...
Hello,
I had an electrician install a 100Amp subpanel which feeds a mini split. I addition I added a Homeline 50A GFCI breaker to power a shed. I ran 80feet of 6/3 direct burial cable into a breaker panel in the shed. Here I tied the Neutral and Ground on the same bar. Neutral and ground are not...
