Hi there, firstly, I'm new to the forums, and incredibly un-knowledgeable about electrics, please excuse my ignorance, I'm trying to learn!
I'm trying to build a string of 7 40Watt light bulbs, each a metre and a half apart. By this I mean I bought 7 light bulb fittings (standard cheap bayonet style, unearthed), 7 lightbulbs, a plug and 3A fuse and some 2way wire (as recommended by the DIY shop I bought it in for making light fittings) and wired it all together.
I thought nothing could go wrong or be wired incorrectly, a simply enough job, just the 2 wires coming out of the plug, into the first fitting, out of that, into the second and so on.
I appear to have wired it correctly, in the sense that plugging it in means that all 7 lightbulbs light up.
However, they won't all stay on for log, before the fuse goes pop. Replacing the fuse means they all light up again, however its not long before it goes once more.
I'll be honest, I've NO idea why. It could simply be that 7 light bulbs from one plug is too much of a load on the 3A fuse?
Would a 5A or 13A be better for the job? Or would thew wrong ampage blow the bulbs? (I'm afraid I have no idea what the ampage on a fuse means in real terms to me, I've tried reading the articles on Wikipedia etc and still can't quite work out what it all means in this context.)
If there's no particular reason why a 3A plug can't run 7 40watt light bulbs, what other reasons could there be? I'm afraid I'm really in the dark here (literally lol)
Any suggestions or help would be very much appreciated. Thanks in advance!
