    a solar powered street lamp.

    Though a quick Google seems to indicate it is a commercial thing - uses LEDs to run on lower power, not sure where the battery is.
    And they (there were two or three) were on an industrial estate, not the actual street.
    And could, I suppose, be a test installation...

    Interesting there appears to be no photocell (unless it's hiding behind the PVA). Dodgy bit of unsupported wiring there too! Wouldn't put my name to that job!

    Possibly all controlled from a single photocell on a nearby roof? Or one of the (much higher) lamp-posts a few yards away on the actual street? Or even a timer?

    Switching, however it is done, would have to be between the power source and the lamp though, so unlikely to be remote.

    Bluetooth? ;)

    Actually, I think most of the street lights round here are on timers, so most likely that.

    Did you used to be a plumber/builder?!

    I am still an electrician by trade, although not really practising anymore. I've turned my attention to fire alarm systems. I have known Builders who will have a go at wiring though :rolleyes: Used to get regular calls to go and put it right!

    Having just had my kitchen re done together with some building work, there was quite clear evidence of the last builder having had a go at his own wiring. I am surprised the house hadn't burned down.One of the plug sockets in the kitchen, connected to a metal American Style fridge/freezer, wasn't even earthed. Certainly explained the ever so slight tingling/staticy feeling when touching certain parts of the fridge! Many £'s later and all fixed.

    Lots of street furniture gizmos are powered by solar nowadays, pollution monitors, streetlights etc.

    He should be jailed for putting a circuit in with no earth path back. That earth connection will save your life. It makes me so angry that this still goes on.

    I'm too scared to ask someone to review our wiring, can't afford to get it replaced, but the previous owner of our house was clearly happy to have a go at a lot of stuff himself, never mind the builder. I know it needs doing, but the cost ... argh (and it's always the tip of the iceberg, re-do kitchen wiring? yes, but you'll have to replace the floor, the cupboards, re-plaster and buy a new cooker).

    No idea who had done that. Only when the electrician came to sort out the other stuff did he find thst when replacing the fascias for us. There was an earth wire connected to the socket but the other end wasn't connected to an earth. He only found it when testing the circuit once he had connected back up to a new socket and used his testing machine thingy.

    Not good. Should a live wire come up against a metal appliance casing, (toaster, washing machine etc)the earth wire provides a path for the electricity to flow in order to trip the MCB/blow the fuse. If the electricity has nowhere to flow to, it sits there quite happily until you touch the casing, then hey presto, you become the new earth wire!!

    Is there a quick reliable way to test the wiring in a house?
     
  15. Craig20264

    Craig20264 Well-Known Member

    If you have the right equipment, and knowledge. Yes.

    Why not use the output, or lack of, from the solar panels to control the lamp?
     
  19. Craig20264

    Well yes, but you still need a means of switching the lamp on/off at the required times, whether that be a timer, (pointless really as it would need constant adjustment), or a photocell. A bit hit and miss to use the fluctuating output of the panels. I suppose it's possible with the right circuitry and components, but more costly than a photocell I would think.
