    Lamp "tap" switch is switching on by itself

    Interference in the mains can make these things go belly-up. Electrical noise from unsuppressed series motors, electric welders etc etc. May not be in your residence.

    Solar setup question

    Your block diagram does not make sense. The part that stands out is the "mains" block. I have brought this to your attention previously so will not comment further. You obviously have no idea of the complexity of any system regarding multiple sources of generation and have been advised to keep...

    Backfeed anything at all into the mains without authorisation and the supply authority will take you to the cleaners. Be warned.

    3-phase ac wind generator problems

    No. Your discription does not make sense. One cannot put dc into a rectifier bank and get ac out. Also I have no idea what your diversion load is. A circuit diagram would be more help. Diodes appear to be pressed in type but only disconnection of the bridging straps and testing to enable a...

    Old silent chap

    If you have an old amp or small transistor radio or similar, you could make yourself a basic RF/AF signal tracer. Might make life a bit easier. Failing that, here is a link to an easy one to build yourself. https://xtronic.org/circuit/audio/circuit-audio-rf-signal-investigator-lm386/

    Copper Clad Aluminum vs Oxygen Free Copper use, trade off, voltage drop in DC circuits.

    You will find many arguments for and against but the fact that copper will carry a given current at a given size more efficently cannot be denied. As far as your tests go, any done under no-load conditions are useless, don't mean a cracker. It is usual to use bi-metal lugs if joining any...

    need source of inexpensive solenoids

    Some commercial printers use small solenoids. Usually mounted in a plastic rack of 6 units. However none operate at 5v like you require. Reason for this is, to keep them small, obviously the windings have to take up very little space. Therefore they wind only minimum turns, run them at 24v BUT...

    Sounds like you made a wrong connection and fried something in the power on section.

    Relay dry contact

    There are 2 instances but since you mention one I will explain that first. Wet contact in the context of voltage free means there is no voltage applied by the controlling circuit. Ideal for complete isolation from the controlling section. An example would be between 12v control and 240v mains...

    Underwater Help

    Posting a link or 2 to your references might get a bit more assistance. Current illustrations are rather vague especially since you are requiring technical assistance.
