Installing a bonding conductor (preferably a dedicated one) from the pump to the shed's earthing system will take care of any differences of potential between the two earthing systems. I would also want to see warning labels installed; both at pump and at shed MSB. That's because anyone turning off...

I have a situation with an electrical installation supplying an electrical accessory in another installation. There is an orchard with its own supply to a shed. A house has been built on the orchard land and has its own seperate supply. There is a pump in the orchard shed to supply water to the hous...

Hi, just looking for some help in determining compliance for an installation or advice on configuration. The property has a meter board on the fence line with earth electrode etc. There were 2 seperate buildings fed from the meter board with their own switchboards and earth electrodes. Currently a n...

Thanks for the info. I did issue a CoC for the work but reading 6A wondered if it was required. I was unable to find something that defined replacement so was a grey area. 59(3)b makes it much clearer that if you are replacing something then you would need to maintain it in its original condition.

Just wanting to get some clarification on low risk work. “6A Meaning of low-risk, high-risk, and general prescribed electrical work (1) In these regulations, low-risk prescribed electrical work— (a) means prescribed electrical work that comprises the maintenance or replacement of a fitting in an exi...

I thought the requirements seemed a little unnecessary, so thanks for the input in working through it.

Just wanting some thoughts on the origin of the FSC for EVSE. The first quote below is from the addendum to the work safe guidelines and the second from AS/NZS 3000:2018. “3. Where an EVSE is installed at a residential installation, the charging final subcircuit shall be protected by a type B RcD an...

I have tried to work through this myself and have gone through the old post a few times. I think you can say that the barrier for fig 6.7 is most likely a shower screen even though you are not given that information. The figure shows the barrier stopping all zones except for wrap around indicating t...

I understand where he is coming from though. I think there is a really inconsistent training provided to apprentice electricians. A large portion of off job training is not relevant to a lot of electricians on the job. Then depending on the scope of work your employer does you may be really lacking ...

Thanks for the clarification Jamie. So even though it doesn’t need to be earthed then PEC still needs to be there as required by 5.4.3.

I see what your saying now Jamie.

The clause is written in such a way that the addition of socket outlets require RCD protection regardless of if they would have been required in a new installation or not. That makes things interesting.

I must protect the socket outlet via RCD as per 2.6.3.4 Am I missing anything? Or just a flaw in the wording? Does exception 3 of 2.6.3.4 not cover this? Seems to me like it is saying when adding socket outlets to an existing sub circuit where an exception from 2.6.3.1 or 2.6.3.2 would apply then R...

I have a question about the requirement for an earth at a lighting point in an existing installation wired in 2 core. 5.4.3 requires an earthing conductor at every lighting point. If I was just replacing a fitting I would not be required to earth the fitting unless the fitting required it. However i...

Thanks guys for the help and background information. I new there must have been something allowing this as Doug said this is a situation commonly seen. AlecK section 2.5.3.4 b i was exactly what I was looking for. The problem was I had read it but never really comprehended it properly due to the way...

I had a situation where I was re-wiring a house and one of the sockets was wired from the switchboard in 2.5. From this socket there was another socket wired in 1.5. The second socket was in a position where it could not be rewired without running the cable on the surface with protection, the owner ...
