Interface Posted March 17, 2018 Share Posted March 17, 2018 Is it ok to put an extension lead between the wall socket and a lead that is attached to a powerboard? It's just that over the years with different equipment the manuals have said plug direct into wall socket, no extension. My current powerboard has a lead that is only 1 metre long and even though everything connects just ok it would be much better if I could put a 1.0m extension in.

Darren69 Posted March 17, 2018 Share Posted March 17, 2018 Yes, lots of potential scenarios. My shed system is powered this way, no issues. Extension lead to a power board above the work bench/stereo system. Link to comment Share on other sites More sharing options...

Cheers, Interface Unless you're using a high-grade powerboard (there aren't many around), it won't make any difference if the powerboard is plugged directly into the wall ... or via a 1m extension cable. If you really want to get maximum SQ: get a sparkie to put several 2-way wall sockets on the wall - instead of the single one you have the powerboard plugged into (or use some 4-way wall-sockets). then have a power cord going from a wall socket to each component.

Interface Posted March 17, 2018 Author Share Posted March 17, 2018 Thanks for all your responses. Perhaps I should have been more clear in my post. I did not want to know if there would be a change in SQ. What I was after if there would be any physical issues like overheating of the extenion lead or any thing that would be detrimental. Thanks again. @andyr, @Darren69 1 Link to comment Share on other sites More sharing options...

Andy Unless you use a very long extension lead, and the excess length is coiled up. Then it can heat and be dangerous. Always use an appropriate length, and there won't be problems.

And increased temperatures results in increased agitation of atoms/electrons in the conductor causing greater resistance, which produces more heat. May not be applicable in in the OP's situation but maybe handy for some newbies to know. Link to comment Share on other sites More sharing options...

It's physics, David. Edit: have a read here, or check out one of the multitude of links that will explain the same effect in regards to what is going on with resistivity and rising temperatures. http://winnerscience.com/2011/12/01/variation-of-resistivity-with-temperature-of-metals-or-conductors-semiconductors-and-insulators/ Have fun Edited March 19, 2018 by Muon N' Link to comment Share on other sites More sharing options...
LogicprObe Posted March 19, 2018 Share Posted March 19, 2018 You could get a custom ext cord made up. It's just that most off the shelf cord might have trouble handling high currents for extended periods. Link to comment Share on other sites More sharing options...

Assuming, it's a well made and aussie standard lead, then absolutely (110%) not. If you are concerned about your 1m lead.... do an experiment. Get a heater, or hair dryer, or something. Plug that into your 1m xtension lead, and into the same power point as your stereo.... let rip, and make sure everything is fine for 15, 60, 600 minutes. whatever. These devices draw much more power than your stereo, and so you will know you will be fine. My experience: I draw 10amps over a long (well made) extension cord 24/7, and everything is just fine.

I agree Dave. I use a 5 metre extension cord to power a pool pump. I bought a water resistant heavy duty one and it's been working just fine for the last 5 years.

davewantsmoore Posted March 19, 2018 Share Posted March 19, 2018 Geee... Can pool pumps really draw a constant 10 amps? ... even if they only run a few hours a day, then that's expensive. Being a Tassie, I'm not real familiar with pools. Link to comment Share on other sites More sharing options...

Ooh yeah, I hear from owners about a power bill that's 300-400 bucks more, per quarter, since they put the pool in. Over 1k a year at least.
