Not about lighting but....
If I run a 75m extension lead from my temporary power pole to my shed, is there going to be any loss of power along this distance?
Thanks

Thanks JB A little, but I ran our factory like that for the 4 months it took to get power... same distance.

Ed Thanks for the response Ed JB Re: Question for an electrician or electrical expert 4May 08, 2009 6:25 am It all depends on voltage drop. Usually most extension leads use 1.5mm2 cable and are no longer than 30 metres long. Your best bet is to talk to an electrician and get them too calculate your load and give you an idea of cable size. You may have to use a 4mm2 or 6mm2 cable to do the job. Re: Question for an electrician or electrical expert 5May 08, 2009 7:10 am It really depends on what load you are running at the end of the 75m... To give you a example.... If it is 1.5mm2 Cable... And you are drawing the full 10A... Then you would see around 25 Volts lost to the cable.... So instead of getting 240V, you'd have 215V... If its 2.5mm2 Heavy Duty Extension lead this reduces down to around 14 Volts.... Again this is at the full 10A loading... If it's only 5A, then halve these numbers.... Electrical Engineer...

The question like people have mentioned above is what do you plan on running. If you are running high current devices like a compressor this will be an issue. I was planning on running a laptop, a kettle occasionally and small power tools eg drill, electric saw. And a light or 2. Probably not all at once.

Changed over to a thicker (Home made lead) and it was fine. You could ask an electrician to wire multiple el cheapo leads in parallel.
