How are you guys .
lt would be really handy if l could run an extension cord 120 mtrs to run a circular saw from . lt's only one of the smaller saws . 1200 l think !
ls that safe ?
cheers.

No

ass:D :D :D
Sorry Jack:D
The length of the extension cord, actual distance depends on the cord you use.:DQuote:

Huh? If you can't run it that far; how the bloody hell do they light up the Mooon when it's full.:confused:
;)
It really depends on how fit it is.
Cliff, don't you know that the moon has it's own generator?
voltage drop and current availability are the 2 issues, this can be tested by an electrician with a volt meter and amp meter
If you use 30 amp cable you can run it safely for 50-60 meters and drag 15-20 amps continually
but to make a cord this length is costly $100-$200 as you need special plugs to take the thickness
I had 1 made 8 years ago for working in the building industry, the trouble now is you are only allowed to have an extension cord 30 meters long

With 1200 Watts you'll be dragging 5 amps but you will loose voltage over the run and each connection so it may drop the performance down a bit. If it's only a one off use you may get away with it ok. I use a whipper snipper on two 30m leads with no hassles. If it's to a shed for long term see Cliffs thread.
I have on a couple of occasions had to run my concrete edging machine on 3 x 30m leads. it draws a lot of power and the decrease in performance of the machine is noticeable. I wont run it for long on 3 leads (would rather load the quote and hire a generator rather than risk the machinery)
ls that a ' no way Jack ' you silly prick type of serious answer by spontaneously combusting interconnected posting quads or what !
Anyway thanks for the help guys - um l think . l have joined two or three leads myself a few times , no hassles but this would be for a few mths x a few hours a day on off type use as l need to cut . Spose another way if that's a no no is cut the timbers up at the house then take them down to fit but it would be much easier down there . l'm turning it into a cabin so l might be a while !
Cheers

If it's only 1200w that you need (plus an allowance for start-up loading), it may be worth buying an el cheapo GMC gen set...
New invention......Latest thing out..........Will solve your problem
It's called....
A Hand Saw :p
No wonder you call yourself a Masterblaster. :mad: In one sentence you have a blast against four well respected members. :mad: :mad: :mad:Quote:

Perhaps a cheep petrol Generator at the site then you can use a short lead, saw some cheep ones at bunnies a while back, and you might get some use out of it later.
Rgds
to run a 1200 watt saw you need a 2.4 kva petrol generator or an 1.8kva diesel generator.
Temite thanks you helped create a brainwave . Why not invest in a battery circular saw . Easier than a genny ' and l wouldn't have to get the power on till l'm ready , couldn't see a problem right !
Hey Sturdee . Mate my attempt at humour via email , better glue in a smiley face next time yeah .
Mater Blaster , when nothing else works l try the hammer . Saved the day many a time but then l'm a signwriter so we have to make allowances .

Good idea Jack for without it we don't know if it is tongue in cheek:D :D :D or foot in mouth.:D :D :DQuote:

Too high i'm afraid :no:
A bit late fellows, Masterblaster hasn't been on the board since October last year.:D
Peter.
Steve hasn't been here for a while either. :)
Seeing that it seems to be the season of the walking dead...and there has been some recent BS posted.
It is not legal in australia to make or use an extension cord less than 1mm2
thet is a 10 amp lead.
a 15 amp lead is 1.5mm2
a 25amp lead is 2.5mm2
those are the commonly available approved felxible cords available for use in extension cords.
the term heavy duty in relation to electrical fles pertains only to the outer onsulation which is heavier.
True voltage drop is an issue and a much bigger issue than most would like to think.
But the limiting factor is is earth resistance.
I cant remenber the detail (I'd have to check tables)
but the limitation on the length of a single extension is the earth resistance required by the standard.
for instance it is impossible to make a legal 100m 10 amp extension cord using 10 amp flex. it simply will not spec up.
even 50 metre wont do it.
As far as i'm concerned any extension cord with 10 amp plugs longer than 20m, I'll be making it on 15 amp cable.
Most of the 30 metre 10 amp builders leads sold by the tool shops these days are made on 15 amp cable.
running realy long lengths of extension cord is something that should be frownd upon. Further has become very hard to do it legaly under the current regs.
BTW have you seen the price of 2.5mm2 flex.
cheers
Voltages and currents are of a bit different values here, however here is what I've done.
I needed to do some welding on my neighbor's gate. My wire welder is a 115 volt and up to 20 ampere machine. The neighbor didn't have a 20 amp plug available so I used an extension cord of 25 feet and 14 gauge. I really couldn't draw a satisfactory arc at all.
What I had was a box of 250 feet (76M) of 12 gauge wire intended for in the wall wiring. I did not desire to cut this wire as it was planned for a project in the shop. I put a plug on one end of the 12 gauge wire and an outlet (power point) on the other end. I welded my neighbor's gate without a problem.
This technique may be a solution to your problem.
Generator option is a good one, Battery Saw is better, Handsaw is a good one as well but.... Another offering of suggestion is with a Power inverter plugged into your truck/tractor battery to produce elec. AC current whilst you are sawing. I
have made such long runs with a spool of Romex, although only a 250 ft. distance (#12/2 w/G) wired wth a duplex receptical and wired to the main box, when building a shed to be wired later.
Yeh fellas that might be all fine a beaut in the US.
here our electrical regs are very much stricter
And the consequences of getting it wrong are 4 times as bad because the voltage is twice as high.
the use of non flex cables for even properly installed tempoary wiring is forbidden.
the use of paralell flexes is specificaly forbidden.
the penalty for most infringements of this type in QLD is 40 penalty units for each offence a penalty unit currently sits at $75.
the possesion of a non compliant item is one offence, the use of it is another, allowing someone else to use it is another.
It is possible for them to hit you five times for the same bit of sillyness if they want to because of the way the offences are framed in the act.
the electrical legeslation in QLD is some of the most agressive in the world.
Man they'll stand you up & kick you in the bum, turn you arround and kick you again
best option is either a battey powered or hand powered tool.
Or a generator.
Interestingly in QLD the use of inverters to power 240 volt tools is specificaly forbidden on building sites.
cheers
Is this a rhetorical question?
