Hi All.
I was just after some advice. After working in industry for a fair time, I’m now looking to break into the domestic installation side. I have most qualifications required but my NVQ Level 3 is in electrical maintenance. This is affecting my gold card. Any ideas of what’s required to...

Im not so much up to date with Australian standards in regards to domestic installations. I know about testing requirements after a full installation and I know that there is an actual as 3001 for caravans but I just want to check what testing would be required after say an caravan aircon...
Hi Guys.
Napit sent me an email with requirements for my first assessment via zoom.
Does anyone have any idea what they can ask me for 2 hours !?!
Especially I have on site assessment next day.
Also they asked me to prepare:
Thank you for confirming this ‘office’ meeting.
Please make the...
Hi Im working in a staffed residential home (for severe learning difficulties/disabilities residents) they have a new onsite tanked gas supply being installed to supply two domestic sized gas boilers in seperate locations, which will replace the existing big oil fired boiler. I need to clarify...
Evening All. I've been having a debate (argument) on a FB group with another well respected spark, and my old tutor. The subject of discussion - supplementary bonding.
Their opinion is that it is required throughout an installation, where ever the conditions in 415.2.2 cannot be met without...
Good Day;
I am installing an external portable 4KW, 30A generator to my small mountain cabin. I have accounted for an external generator hook point, external 30A fused disconnect leading to the internal 12-way Square-D power distribution board. An external 4ft copper ground rod provides the...
Hi Guys. Firstly, am glad to join the group. Secondly I am very curious to hear from those who have TNC-S as their electrical supply I have 2 questions (1) Are you required to install an earth rod (stake or mesh) on the homeowners property? and (2) what are your regulations regarding its...
Many will by now have heard of the new requirements for private landlords, enacted under Statutory Instrument 2020 No. 312, known as ‘The Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020.’
All new tenancies, and all existing tenancies from 1 April 2021, must...
Why do circuits 32 amps and under require a 0.4 second disconnection time at 230 volts, but circuits over 32 amps are legally allowed 5 seconds? 115 volts for 5 seconds is enough to cause injury to the human body.
Hey All,
new member here. I work as an industrial Sparky in the supply industry and am a qualified EFM but because it's not my day job I know very little about domestic installation and especially PV regulations. I had Solar installed on my house last year and I've recently read a few ESO...
I have been looking around and used a calculator for this. I am looking to run 120v/100 AMP supply to a pole barn 175 feet and buried from the main breaker. What size and type of wire will I need? Thanks in advance.
Excuse the probably stupid question!
I'm a bit out of date, so not yet up to speed on 18th edition.
Been prepping for a domestic board change, but am confused about whether I need an SPD or not.
Seeing as the majority of suppliers are selling their boards without the SPD, I'm assuming they're...
I'm replacing our oven, and want to make sure the new oven does not exceed the power requirements of the old one, but I can't find it. Our existing EOS66SS2 shows only the following information:
Nominal voltage 220V - 240V ~50Hz
Power connection: 13 A automatic bipolar switch with protected...
Just want someone to sanity check me here; my understanding is that battery powered detectors are not permitted in the private rent sector - they're fine if you own/live in the property yourself but the minute it becomes private rent then the minimum requirement is LD3 - Mains Powered (with or...

Hi,
I want to bring 2 x 20A (@120V) to a chicken coop. It will be powered from my garage panel which will require 140' of cable. 85' in the garage along 2 walls, and 55' buried between the garage and the coop. I used a few voltage drop calculators and it looks like I will need a 6/3 to stay...
Hi, we have a single phase overhead supply to our property, and are constructing a garage with a corner near the center of the ~15m span. What is the minimum separation to the structure? Is it possible to secure the cable at the midway point on the new structure?
Thanks!
Hi,
I want an inverter which can give the consumer power from solar if available, second battery if there is power on it and at last from the grid BUT i am not interested to feed to the grid (not interested in getting an approval from the local energy company). I know there are hybrid inverters...
