[Uncle StoatWarbler]

Never seen a rivetted PC power supply case yet - usually 4 countersunk
philips or pozidrive screws. I have opened many to replace fans (or to
salvage the fans out of dead PSUs)

The original IBM PeeCee PSU cases were riveted or sealed using special
notchless screws.

ATX PSUs are sealed for the purposes of electrical registration
requirements.

AT power supplies (cable to front of machine and power switch there) are
not and anyone working on these should be a registered electrical
serviceman.

The certification isn't expensive or difficult. I had class A and B,
electrical certification however I haven't renewed it (It needs to be done
every year.)

You only need class B to work on 400V fixed wiring and high power devices.
Nothing in the average home requires it unless you have a 3-phase welding
shop in your garage.

They have External 240 connected to a Switch and they are easy to open 4
screws..

If you go to

and look at Technical Corner (page two) you will see the following

..........

Q: A friend of mine repairs computers and says
that he does not require registration. What is
the situation regarding the need for registration for
carrying out such work?

A: Registration is required for the carrying out of
"prescribed electrical work" and working on an
electrical appliance such as a computer is deemed not
to be within this category provided that "the work can
be undertaken without removing screens, covers, or the
like designed to prevent inadvertent contact with fittings
intended to be supplied at voltages above extra low
voltage". Refer to regulation 17 2(b).
In a practical sense this means that, except for the
power supply module, most work on a computer is not
"prescribed electrical work".

............

In my experience the external switch contacts on a psu are generally
covered with insulation that comes within the description of a screen,
cover or the like. If they aren't then registration is required. It is
up to you to use your discretion.

If you look around you, you will see many examples of mains appliances
that use screws to prevent people coming into contact with live
conductors. So long as a tool is required for removal then that is
accepted as meeting the requirements.

If you want to check who on this ng has registration then go to

www.ewr.govt.nz

Of course you'll only see those that post using their real name.

Regards
Malcolm.

Most are not covered, plus most here have posted Facts that the open the PSU
to replace the Fan..

That mean bugger all, all gobblegook, they remove the screws to replace the
Fan..

 

[Richard Malcolm-Smith]

As long as he is not modifying the PSU, then he should not need

certification to work on 240V equipment... there was a case about this
recently in the herald. The general answer was, that all the rest of the
stuff that this guy had worked on was 5/7/12 and so no cert was needed.

URL for that one?

I too have not seen a "riveted" Power Supply.

They do exist, tho not that common at all.

They're just pop rivets, like some of the
case bits are rivetted and not screwed.

In my they've all been screwed.

I'm not silly enough to go there.

Bullshit, hardly any are.

Mindlessly silly.

 

[Rod Speed]

Donkey.

they have a external Main switch

Modern ATX supplys dont.

and people here have stated that they do replace
the Fan, never ever seen a sealed one yet..

You wanna get out more.

They are all trying to cover up that they
have no permit to work on them at all.

Dont need one with an ATX supply, even in sheep-raper-land.

 

[Rod Speed]

They have External 240 connected to a Switch

Like hell ATX supplys do. No 240V anywhere outside the power supply.

Very true another Gov Tax plus you have to do a Day refresher course every 2
years..

Move Gov Tax..


The Main problem is most stuff here have never been approved or tested for use
here, another Gov cop out..

So you are trying to coverup that you do not have any registration,

most posters here have stated that they open them up to replace the Fan..

Mindless petty bureaucracy gone completely
mad. We dont even require anything like that
with full electricians in this country.

Move Gov Tax..

We do have the tax, license fees ongoing etc.

The Main problem is most stuff here have never been
approved or tested for use here, another Gov cop out..

I dont see it makes any sense for tiny little countrys
or even countrys the size of Aust to test everything.

I suggest that you stop referring to Australia like that.

Sorry to butt in here guys, but according to my husband ( who IS a
registered Electrical Inspector) anyone holding any form of Electrical
registration is on the Register of Electrical Workers. found here
http://www.ewr.govt.nz/pls/web/dbssiten.main just click on Electrical
workers register and then search for Roger Sheppard or whoever he
claims to be.

Heh. He doesn't exist. Maybe I should look for Wodger?

 

[EMB]

I think it would be very wise for these posters to front up and be checked, so
why just pick on Woger.?

Or is it just a Witch hunt.?

The more people you piss off, the more people are likely to cause you grief.
Woger has abused, insulted and been rude to most of the regulars here - it's
not a witch hunt, just natural justice. Oh, and my offsider's name is on
the list - keeps us all legal beagle.

Because Wodger is the only person here who claims he's registered.

[Mainlander]

Bollocks, you are so full of Crap..

Not in the Case of the Older PC , they have a external Mains switch, and Many
here have stated that they have replace the PSU Fan, I have never ever seen a
Riveted PSU..


You are Full of Bull.

Please go back and read what I said.
MODERN PC is what I said. You can see it there as plain as day.

If you don't open the power supply case, then you don't require
electrical registration to work on a modern PC.

 

[Mainlander]

They have External 240 connected to a Switch and they are easy to open 4
screws..

Sorry Roger, I said "MODERN PC". All modern PCs have all the 230V power
(note that it is 230V in New Zealand) sealed away in the power supply
case. When you open a PC case, that 230V power supply is all sealed up,
and unless you open the power supply case separately, you are not
required to have electrical certification to work on the PC.

It is not possible when opening a PC case that has the fully enclosed
power supply, with no external 230V terminals that can be contacted
without the use of tools, to accidentally come into contact with 230VAC.
This meets the requirements of the electricity department regulations and
thus, working on any electrical appliance that does not contain any live
bare 230VAC electrical contacts or terminals does not require any
electrical certification.

There are regulations that specify that where voltages are present and
can be contacted, you are allowed to work without registration up to a
certain voltage level. The voltage of max 12 V found in PCs is well
within these limits. Some devices such as modems may however contain
voltages of up to 50 VDC or 70 VAC. An exemption has been made in NZ law
for working on telecommunications equipment that contains these voltages.
