misterbassman Posted January 27, 2004 Share Posted January 27, 2004 Hi everyone, Are there any sparkys out there? Just wanted to double check what the accepted power rating is on 1.0 mm squared mains cable. cheers Link to comment Share on other sites More sharing options...
Stu Posted January 27, 2004 Share Posted January 27, 2004 A google chucks up 6A as a figure on alot of sites, but please make sure someone else confirms this, as I'm not a 100% sure. Try playing around with search strings in Google and see what it chucks up. Stu Link to comment Share on other sites More sharing options...
Brian Posted January 27, 2004 Share Posted January 27, 2004 Just wanted to double check what the accepted power rating is on 1.0 mm squared mains cable.flex or T&E install cable? PVC or Rubber? How many cores? etc etc 3-core PVC Flex, 3182Y, 10 AmpsT&E, 6242Y, 13/17 Amps Link to comment Share on other sites More sharing options...
Conscript Posted January 27, 2004 Share Posted January 27, 2004 RS states that 3183Y 1.0mm2 can take 10A. They also sell moulded IEC leads with 13A plug fused at 13A and 10A IEC sockets connected together with 1.0mm2 cable. Can anyone tell me where the 3A goes and how to get a PAT certificate on RS 426-373 for instance? Link to comment Share on other sites More sharing options...
Jivemaster Posted January 27, 2004 Share Posted January 27, 2004 Current carrying capacity varies according to conductor size, insulation material. and location ventilation. 1mm 3 core pvc flex is good for 10 amps in free air, tape it into a multicable assembly and the heat builds up so the rating goes down.

So it's not a problem giving it a PAT certificate. Link to comment Share on other sites More sharing options...

The potential is then there to draw more than 10A down the cable. Link to comment Share on other sites More sharing options...

Brian Posted January 27, 2004 Share Posted January 27, 2004 Ah, found what I was looking for... IEC320 (which is the standard for what we call IEC connectors) allow the use of 0.75 sq mm cable for DETACHABLE power cords fitted with 10A connectors as long as it is no more than 2m long. It also allows 1.0 sq mm cable fitted with 16A IEC 320 connectors, again no more than 2m long. It's also worth noting that IEC65 (EN60065) allows cables to rise 60 deg C above ambient in normal operation!!! EDIT... Mind you, the whole situation is a mess because at least two other standards disagree. In an ideal world we would put 10A fuses in our cord sets (actually Bulgin ones can be ordered with 10A fuses).

Brian Posted January 27, 2004 Share Posted January 27, 2004 Well, the better ones are fused, yes - but what about something like this?True, I'd forgotten those things. But in the end you'll still only get 13A down the cable which will not cause a problem (see my comment in the post above about temperature rises).

MarcT Posted January 27, 2004 Share Posted January 27, 2004 In an ideal world we would put 10A fuses in our cord sets Like this one? http://www.dragonfly.plus.com/fuses.jpg Yup - that's a BS1362 10A fuse, alongside a 2A one, and a 13A one for comparison. I have no idea where I got these - I found them in my toolbox during a clearout at the weekend (along with a blown 60W half silvered spot bulb I'd been carring around for the last 6 years...) Its amazing what crud accumulates in the bottom of a toolbox. Marc Link to comment Share on other sites More sharing options...
Brian Posted January 28, 2004 Share Posted January 28, 2004 Like this one? Yup - that's a BS1362 10A fuse, alongside a 2A one, and a 13A one for comparison.The pic didn't work but 10A fuses are easy to get, your high street might not stock them but RS and Farnell do.

Andrew C Posted January 28, 2004 Share Posted January 28, 2004 The IEE in the PAT COP recommend fitting either 3A or 13A. I really don't see it myself, but that's what it says. Link to comment Share on other sites More sharing options...
