Licensed electrical contractors have the equipment and knowledge to safely do electrical work.

When using a tradesperson for any electrical work you should ensure:

they hold an appropriate South Australian license
they issue you an electrical certificate of compliance.

This applies to all electrical work on your property regardless of whether it is your home, rental property, commercial premises, caravan or boat.


Do you have them change the batteries in your flashlight, too?

Just more hype for the overly paid, lazy, sloppy work and don't follow

code 50% of the time licensed electricians. They think that license is
the ticket to insure their income and screw every one else that actually
does a better job at it.

Those that come in here preaching like that are generally affiliated
with the licensed trades and is just trying to drum up more business
because they know the score and so don't everyone else that has a brain
on their shoulders.

The majority of unlicensed people I've seen performing those jobs
tend to do a much better job at it, because they go by the book and do
nice looking work.

We know. In the last 2 years, we have fired 3 electrical contractors
in our facility. THe last one made a comment when being confronted about
doing shabby work, about our electricians in house not being licensed.
That was the magic statement that got that contractor fired.

We have a contractor plumber that is starting to use that approach, I
think his days are also numbered.

We only hire in these guys for things that our boys are to busy to
get to or too big of job. However, because these guys are not employees
of our facility, we must bring in licensed people, no matter the trade.

It's fun sorted out the licensed welfare contractors.

Unlicensed work is illegal and extremely dangerous.

Whether work is dangerous is not a function of whether it's done by a
licensed electrician, it's a function of whether it's done competently.
I've seen highly questionable work done by licensed tradesmen.

Licensed electrical contractors have the equipment and knowledge to safely do electrical work.

Maybe. Doesn't mean they actually do it safely.

When using a tradesperson for any electrical work you should ensure:

they hold an appropriate South Australian license

Even when not in South Australia?

they issue you an electrical certificate of compliance.

This applies to all electrical work on your property regardless of whether it is your home,
rental property, commercial premises, caravan or boat.

Laws vary. In NSW I can lawfully work on gear as long as it's not
permanently wired up. Other Australian states take a more nannyish view.
In QLD, for example, you can't even attach a plug to a power lead.

Insurance companies may not cover fire or public liability claims caused by do-it-yourself or
unlicensed installations.

Show me a policy that contains such an exclusion. People buy insurance
to cover risks. If a policy contained exclusions such that my
inadvertent breach of some law could render the policy void, then I
wouldn't touch it with a barge pole because it wouldn't be doing the job
I was buying it for.

http://fallonservices.com/_blog/Handy_Hints/post/Is_It_Illegal_For_Me...

The web page of a company that's selling electrical installation
services is hardly likely to be the most authoritative when it comes to
telling people whether they can do something themselves.

It's illegal anywhere in Australia - not that it's stopping anyone...

Unlicensed work on fixed installations is unlawful over most of
Australia (even then, there are some exclusions). The situation for
other work varies.

false Hype.

Bull shit, I've seen real shitty equipment being used by overly paid

licensed electricians. You would be surprised at how many licensed
electricians out there that really do not understand the majority of
what they do. They are like number painters, remove the numbers and
they're screwed!

When using a tradesperson for any electrical work you should ensure:

This only works to push out those that actually do better work..

My how your GOV officials are so easily fooled!

we are allowed to do our own work on our properties.

Insurance companies don't care either way, because the first thing

they do is reject a claim and make you wait hoping that you, the home
owner will foot the bill while winter time is coming, to get your home
repaired.
Insurance companies have many lawyers on their side to deny clams no
matter what if they don't feel like paying for it, also, most electrical
fires are from defective consumer products plugged in and the insurance
company also knows this. So go such an egg.

I actually have a copy of the San Francisco Building Code, and I've

Purely a jurisdiction issue. You live in one of our socialist paradises,

I got a gas plumbing permit. While i was at the city hall, i asked if

In Vermont they kept permits but there is about zero enforcement, or paper
trail, evidently. When I sold my house I needed the CO, which there was no
record of ever completed being completed. They "assumed" I was legal because
the house had been standing for 20 years. Unfortunately, the permit was only
for a two bedroom house and mine clearly had three. I had to fork over
another $4000 for the third bedroom. Pissed me off, it did. Vermont sucks.

It depends on which community in the People's Republic of NY.
For example, some years back Mahopac NY would give you a permit
and allow you to do your own work in your own house, if you
passed a test that they gave you to be "licensed" for that
specific work. That's a number of years back - I don't know

Yes, some made you jump through hoops. Some disallowed homeowners from
breathing in their own homes. The still rational ones allowed homeowners to
do their own work unmolested (still have to pass the same inspection for
permitted work). Of course that was ~25 years ago and NY has gone a lot
further down the left swirling bowl since.

They're generally talking about their specific instance. Much of "the code"
doesn't change that much as it relates to home wiring, though. It's not
rocket surgery.

I always hear that, when people running out of reasoning to argue.

Well, when reason fails and all you post is nonsense, like 14 LEDs,
PCBs with connections that go nowhere,

The connections go to the back of the CPU board

http://173.224.223.62/pic32/cpu.jpg

 and a slew of pushbuttons for data entry,

There are additional headers on the PIC32 CPU board for buttons.

Got some rare pinned themisters. Newer one are usualy smd. Cleared
out their inventory; oh well, only 20; wish they had more.

This 10K themister has good response at room temperature. I tie it to
+5V via a 10K resister and took some readings between 60F and 70F
(normal operating range of furnance). Outside ranges are probably not
accurated, but don't care for now. Here is my calibration table.

// maximum value is 1023
int tval[30] = {950, 940, 930, 920, 910, 900, 890, 880, 870, 860, //
50s
850, 840, 828, 812, 805, 790, 775, 760, 750, 740, // 60s
730, 720, 710, 700, 690, 680, 670, 660, 650, 640 // 70s
};

Each room controller (PIC32MX) needs to measure and report it's
temperature and forward commands to hit the fan. Plan A is using USB
WiFi. Got it enumerated and initialized, but don't know what to do
next, i.e. channels, WEP and setups. So, plan B is using USB
Bluetooth. Hopefully, i can setup and pair the USB/BT on another PC
and move it to the PIC. Still waiting for my after chrismas gift to
arrive ...

For the fridge, pobably need a different themisters and/or circuit.
This one does not seem to work too well at low temperature
