SomeoneSomewhere:

 

A nice big E-stop with suitable high-power contacts is also a good option for that.

 

 

 

 

Nope, how will you know that the 4way power point is having 18A run through it until it starts to smoke? Or the wall outlet starts to smoke? Or the 1.5mm cable starts to smoke?

 

Too late the damage is done.

 

Needs to have a current limiting device inline somewhere, that is why most multiboards have an overcurrent trip built in.

The stop switch answer was nothing to do with current limiting, it was related to cutting power to tools while changing blades or making adjustments.

OK here is what we did in the end.

 

Mounted a 4 x switched power board which is connected to male inlet socket. Yes we had to chop off the original plug so to wire it to the male inlet socket. When required we connect the bench up with a Arlec 15m ext cable with built-in RCD safety switch. The wall double power point has a LED light batten and a 4 x switched power board running of it.

 

 

Last week I pulled the front off the switch board and there was two circuits (labelled P3) on the one C20 amp circuit breaker for those areas I mentioned in the above post. As you can see there is no room within the switch board for more circuit breakers or RCD's.

 

The other day we had the washing machine, dryer, saw table, mighty mouse sander and the LED light batten as well as the chest freezer and kitchen fridge running at the same time. There was no trips or warming up of points. The saw table does have a soft start as well.

 





Whilst the difficult we can do immediately, the impossible takes a bit longer. However, miracles you will have to wait for.

You have more room if you get p4 replaced with a couple of RCBOs instead. Swap the lot while you are there to get protection on everything for peace of mind...

I really hope the above picture is a stock photo (the safe answer is yes) you got from somewhere, because as a homeowner you are not allowed to do *any* work on a switchboard.

I can assure you that is a genuine picture of my switchboard. The only work that has been carried out on that board since I have owned the property (2015) was to get a certified electrician from AJ's Electrical Tauranga to install a proper external double point on the patio which he wired into the new RCD (P4) which he installed and on completion provided me with CoC. I have never done any work on a switchboard and wouldn't even dare to do so.

 

What is your concern with this switchboard please ❓

nothing wrong with the switchboard, but FYI the homeowner exemption does not allow access to the inside of the switchboard, posting a picture of an open switchboard and talking about the work you done tends to make people think you were in the switchboard. that's why I indicated to you that it is a "stock photo" and not your actual switchboard.

How else can you switch off the power in your house without opening the door?

EDIT: oh... you meant someone has removed the plate that looks like it should have had that covers up the wires under the circuit breaker panel?

Yes it does have a front cover which the door hinges off. I removed it to find out how much room I had left, if any, in the box for more circuit breakers or RCD's or RCBO's. Plus how many circuits each breaker was handling.

 

 

If you zoom in on the legend you can see that P3 has quite a lot going on and is 2 circuits. The kitchen is spread over P3 & P4

 

At the price I have seen some circuit breakers or RCD's or RCBO's it would be an expensive exercise if I wanted to put JUST the garage on a separate circuit and I would like the kitchen to be on a separate circuit as well (fridge, jug, microwave, coffee machine, frying pan, mixers, 4 x iDevice charging points). I would of course probably need a larger cabinet as well.

 

A relative-in-law has just bought a house and has remodelled her kitchen which had the switchboard tucked away deep in the back of cupboard behind a kitchen door. Behind the back of this cupboard there is also plumbing as well. It cost her just over $1000 to get the switchboard moved to a far more sensible and I dear say legal position. Plumbing and power do not go well together.

 

When I had a double power point put into the 3rd bedroom/office wardrobe for ONT/router the electrician did a complete continuity, load and safety check on all the house circuits and said we were fine and signed off the CoC. So we have had two CoC's done since ownership. But I am still not 100% happy with P3 & P4 so one day may bite the bullet and get it all sorted.

Technically they are only considered one circuit if you run two cables from one breaker, but that's beside the point.

 

RCBOs are under/around $50 now for decent ones, sparkie's price. I would not go with knockoffs for safety equipment; there have been numerous recalls on the generic ones.

 

Moving a main switchboard is a fairly major exercise. You need the lines company to remove and reinstate the pole fuse, an inspector to sign off the mains and main earth, and likely need to extend cables as well. If you have a separate meterbox you *might* be able to isolate it there and save a step. $1k is pretty cheap.

 

 

 

Another option is to stick in a sub-board next to it and move a few circuits over. That's something that can be done by an electrician alone.
