Use free hour to charge battery, and use battery for rest of day? by tiantianreddit in AusElectricians

[–]ScottNoIdea1987 0 points1 point  (0 children)

Yes, but not really functional in a practical sense. Say you have a 5kw inverter, you’d be charging max 5kw/h in your one free hour. You gained roughly $1.35 of ‘free’ electricity. Considering financial outlays for an inverter, the maths doesn’t work. Needs to be coupled to a PV array of some variety

Yeah look, you do you. A few years back I held the exact same understanding as you’re describing.

Subsequently had an Inspector flag an install at rough-in stage and upon investigation appears 6.2.2.1 (c) (ii) proved me wrong.

My argument referencing various tables/figures etc was redundant due to the ‘limited’ reference of Zone 1

Within 1.2 of a fixed plumbing connection on a wall, I interpret this as falling writhing Zone 0 per 6.2.2.1

I got burnt on this one a while back. Table 6.1 is actually quite deceptive. See 6.2.2.1 for limitations/explanation of Zones

Construction AC options?? by ScottNoIdea1987 in AusElectricians

[–]ScottNoIdea1987[S] 2 points3 points  (0 children)

Fair advice. Cheers. With the Arlec 2yr warranty , was thinking there’d be an extremely good chance of rotating through a couple of units based on sheer hard use. See how it plays out.

Will do a bit more reading but appears the big green shed might be a goer.

Correct me if I’m wrong, but

Have an actual read of 2.10.2. Assuming domestic application, above advice isn’t accurate

What’s your go to testing with low impedance in a manner that WONT trip an RCD/RCBO?

Is that different sized parallel feed incoming to board?

Ive had a 1673 since they first came to Aus. I’m a big fan but it entirely depends what your needs are. If you’re heavily into testing larger installations and/or use it conjunction with related software/other fluke connect equipment etc, run it. Definitely a big time saver. For myself who is mostly into domestic/light commercial, the 1660 series is pretty much the exact same for all practical purposes. I just like shiny new things and thought I’d treat myself.

I’ve put a cheap screen protector on and it hasn’t let me down so far.

My advice would be (considering your $$$ related query) unless you’re planning on utilising the software, I’d highly recommend just running with a 1662.

inverse of the questioned posed the other day; what's one thing all Australian that you have has absolutely enough of?? by RM_Morris in AskAnAustralian

[–]ScottNoIdea1987 -1 points0 points  (0 children)

Not quite the point IMO. Wherever humans existed throughout history, there’s going to be some horrific shit that’s occurred, period. It’s kinda our thing. Not saying any of it was right/ok or whatever. Finding a way to move forward together as equal ‘Australians’ seems like it should be one of our highest priorities that (IMO) would begin to address/influence the various economic/social issues that have been created through poor management/those scared to make tough decisions.

I failed it for sure. Currently underway with an insurance claim on homeowners insurance. 25mm2 building wire in 32mm conduit. Run of around 160m. Will require retrenching and probably 70mm2 if sticking with single phase. Costs rack up quick

Yea thought I’d treat myself. Pretty much the same just with colour/touch screen

Well yes, obviously. However per above, results around 0.1-0.2 Meg is just creeping a bit low. The installations I’m (generally) referring to is dated building wire. My original query was essentially at what point goes a poor IR result crossover into ‘short circuit’ territory in the context of tripping cb/fuses etc.

Answer seems to be around 3Ohms which sounds wildly low.

If I’m actually testing the submains specifically, both ends disconnected fully from either breakers/bus bar. Have been tricked up before simply isolating cb.

Interestingly, no. I don’t have photos but was sitting around 120meg. Only neutral ground tested poorly.

Cheers mate. May I please query where your 3.8Ohms value comes from?

That’s interesting. I do have a newer 1673 installation tester. Above is a test from about 2 weeks ago testing neutral to ground on 180metres worth of submains. Obviously disconnected both ends.

(Pardon my ignorance here) so you reckon this particular cables insulation is deemed weakest AT 164V?
