for the sparky's

would you call a VT or CT a transducer? or not really?

OK, for me, a VT is a Commodore, and a CT is a type of transformer winding. Care to elaborate?

If you mean Voltage Transformer or Current Transformer, I would say no, but you could argue otherwise.

If it helps, "transducer" is a term generally applied to a sensor which transforms energy from one form to another. Typically, the second form is an electrical signal, but the first can be just about anything: distance, speed, acceleration, current, voltage, light, temperature, pressure, force, frequency... what have I missed?

Typically, transformers are about transmitting power rather than a "signal", which is where I make the distinction. Others will undoubtedly differ.

never mind i, i did the argument in my head and yes i think a vt and ct is a transducer as they both can convert one signal into another, and maintain isolation.

Arguments in your head? That's a concern.

But it's OK - I don't think barnsey comes in here that much.

on another point, how dodgy can some people be.
my mate just bought a house and i went to check it out with him and i discover that its an asbestos switchboard, not to bad, on closer inspection i can't find a water bond, not to bad, a follow the bare earths (old house) and find the water bond disconnected, and the only problem with that is that the whole house has no earth reference. atleast hes supplied from an MEN pole so his neutral should be 0v.
anyway im putting an earth stake tomorrow, i also traced out a few circuits for him and whoever owned it put some gpo's in under the house, no power there, no worries he just tapped into the light circuit and didn't bother running an earth.

That is why I will never work on houses again....too much dodgy shit to work through, gimme commercial and industrial construction anyday

X2 - I can do fault finding on a $50,000,000 machine but domestic faults have me farked

[84ZOOKSTA]

Wiring in to the lighting circuit is not that bad. atleast the cable is protected with the proper rated fuse/Circuit breaker but an earth would have been nice but whilst i was doing my apprenticeship i was told in the olden days some power points were not wired with and earth as there was some rule that if you could not touch something earthed whilst touching the GPO no earth was required but no sure how true it is.

And my horror story was I had to go and fix a fault at a old house in clayton, The fault was the earth leakage kept tripping, I found the fault in the garage and what i also found there was extra power points wired in with speaker wire(fig8) but not the usual .75mm2 Fig8, it was the stuff that comes with the really cheap car speakers which i think is .20mm2. when i got there all 3 wire (yes he did run an earth) were melted together which was creating a short between Neutral and earth inturn tripping the safety switch.


Just proves what people will do to save money and also why house fires happen.


Sorry for the hijack.

WTF??? It's a freakin' safety hazard!!!

Separate GPOs and lights so an equipment fault doesn't take out the lights - forcing people to stumble around in the dark.

More importantly, how many sparkies will turn off the light circuits when they're working on GPOs?

OK, I know there's additional steps a sparky should take, and he/she probably should turn off the lot, but some tradesmen will take as many shortcuts as bodgy home handymen.

"Not that bad" is not the right phrase. "Could be worse" is possibly more accurate, but "wrong" still strikes me as the best description.

Let's not give the bodgy home handymen any encouragement.

Sorry it was a poor choice of words.

This is bringing back the memories of the S.E.R.F i saw rewired with the fencing wire.

Found this because it took out there service fuse when the fault occured on the oven.

Yeah but where licenced to do that.

are you still working for Logan City, and have you finished Arora yet, and would you work in maryborough for 3 months with weekends off.

anyone know what's doing with the ESO with regards to ELCB's in rental properties, are the owners of the property now required (since 1jul06) to install and ELCB to the gpo's straight away or is it only if a new lease is signed?

[ausoops]

ok i read the eso site more and they are mandatory to be fitted within 3 months. do the eso have any teeth in this matter or will they do their usuall toothless tiger act?

I just sold my place and got in an argument over who was responsible for it. (Not me! ) I think it was for any new tenancy after (some date) or by (some date in) 2008 - whichever comes first.

So if it's new tenants, install now. If it's same tenants (and lease has expired) go periodical for a year or two.

Im working for Nilsen's now Micky. Working on the Southbank Education Precient project....southbank tafe in other words. Working in Maryborough would be nice except for the fact that nearly every night of the week I have something on

Ill let ya know how i go, but i look like picking up a few massive projects all at once.

[Doggy]

oooohhh presumably your massive projects dont include getting your patrol running....thats a 3 year job in itself

any contractors here im after another opinion on this

do you think its too much to have downlights in every room? im doing a mates place and they are cheap as chips now and he is thinking of having four in each bedroom, one in the shitter, 8 in kitchen/dining and 6/8 in lounge, and two on the smaller deck. i am unsure as to whether it will be too in your face, maybe spots for lounge and bedrooms but i don't know what else to put in the kitchen.

[6.5 rangie]

Go for it they look good, better than a batten holder in each room or a flouro in the kitchen

[mickyd555]

We are just completing a house with 73 downlights in it, garage got fluros and outside lights are all up/down tube dichroic lights. They look great and will work well depending on colours chosen for walls. Keep it to eight maximum in each room so you can get them on a 450VA dimmer if needed. Dont use the GU10 240V ones or he will hate you when he needs replacement lamps (they cost a fortune).

I have halogens everywhere already (not one flouro/bayonet globe anywhere.) A few observations/suggestions:

Bedroom 2, any more and it is pain everytime you turn on the lights (Bedside lamp if you need to read). Angle them to try to make them illuminate the wall at the foot of the bed. One in any BIR on a 2 min timer switch (nice touch).

Lounge/TV 2+2 on 2 seperate switches, with a dimmer on the rear set. 20 watt globes in the front set.

Bathroom 2 for the room and one for the bathroom mirror.

Kitchen 3-4 + 2 on 2 switches for full light and midnight munchies light.
