    Cable tray supports needed

    I'd need a C shaped one or my tray will end up vertical rather than flat.

    Cable tray supports needed

    I could do that but they don't offer much side to side support. The whole tray could move sidewsrds and collapse. But I could sort that with 2 diagonal supports.

    Critical load from PV battery

    Sorry yes of course it is. Currently the spec is for a Sofar 3K-6K TLM invertor at 6K No critical as in fridge and freezer. So not critical as such (just the term they use for that specific output.) Interesting that they are now advertised on this very site:-)

    Critical load from PV battery

    Hi folks. I'm having a PV system installed with a 5KW Amasstore GTX5000 Battery. This comes with a critical load output. I have the spec sheet but its not clear if this output is active all the time or only engaged when the grid power goes down. I'm assuming its live all the time (unless the...

    2006 Honda Civic Headlight Switch Buzzing & Headlight bulbs blowing regularly

    Headlights take a lot of power. even 55W bulbs x 2 is 110w at 12V is nearly 10 amps. That's a lot to put through a rotary stalk switch. I'd have expected a relay. However this diagram: Upozorenje o prebacivanju -...
