Main switchboard upgrade

This it the steps though replacing a switchboard. Hopefully, if you are an apprentice new to switchboards, you will find this useful. If you break the job down into parts like i have in the video, then it's not too complicated to do an upgrade in this fashion.
I always found when I was an apprentice that there was a real lack of videos and online resources to help me. I think that most electricians are visual learners, I know I definitely am. So it's hard when we are expected to do 75% of our training in books. Because if this I've set out to start making a library of training and explanations to help my fellow electrical workers in areas they might be having trouble.
Remember, this setup was performed in a controlled environment
by a qualified electrician for learning purposes only. Electricity is dangerous and can kill you. If you are not
qualified, please do not try this at home, just enjoy the learning experience.

Exceptional video and demonstration! Thanks 😊

Hey mate, thought only range appliance doesn't require RCD protection? Can't see anything in anzs 3000 about AC and hot water being exempt unless I'm missing something

[@_nztradie]

@cozzaa good thought I can look but I believe its under fixed wired appliances, But in the 2018 regs when they come in for nz AC hot water and maybe even ranges (not 100% sure) have to be on RCDs

[@cozzaa]

Yeah been in oz and wasn't aware that NZ still uses 2007 so yeah it's not required ( saves a lot of nuisance tripping if you ask me)

[@_nztradie]

@cozzaa yea but we are at the stage that we are behind the times, and it gets a bit ridiculous. With the likes of evs and batteries

Hi mate, could you do a video on wiring a time clock and contactor? Thanks mate

[@_nztradie]

Yea bro that sounds like a good one 🤙

[@IAmThe_RA]

Can the slot with two screws in those copper bars accept a 25mm² conductor?

[@_nztradie]

Yip it sure can

[@IAmThe_RA]

@@_nztradie what is the biggest conductor size the single screw slot can accept? Thanks

[@_nztradie]

@IAmTheD it would be a 6mm² you can get a 4mm² folded over to fit, but the next size after 6mm² is 10mm² and that definitely won't fit in the single screw terminal

[@IAmThe_RA]

@@_nztradie Thanks. What are the size of the mains here and why the 3 MCBs are without RCD protection? Don't you think it's better to replace the three MCBs with RCBOs? Sorry, a lot of questions but I have learned a couple of things from this video 👍

[@_nztradie]

@IAmTheD youre all good bro, it was a 16mm mains here. Some appliances such as heat pumps, ovens, hobs, and hot waters are not required to have rcd protection

[@TradieTrev]

WTF bro? I can do all the meter wiring in OZ, I own myself all the gear to do the job right, no 3rd party need.

What bit are you referring to? The lines company requires us to get one of their certified fuse pullers it you are talking about that
