    Trouble finding 120V DC - 10A breaker.. alternatives..

    Personally I'd prefer to use a fuse. I don't know if they have 10-15 adjustable, but here's a 10a DC breaker.

    Ideas ?

    Or, you could just buy something like this (Csa listed) for about the same price as parts. https://www.amazon.com/POWER-RELIANCE-CONTROLS-MfrPartNo-THP207M/dp/B018A30T8Q

    Trouble finding 120V DC - 10A breaker.. alternatives..

    It doesn't need to be rated exactly120vdc. There's nothing wrong with going to a higher voltage rating such as 250vdc or even 600vdc. The current is the important thing. Selecting the correct current rating is not as simple as just limiting it to the pv arrays maximum rating. I recommend you...

    Connect Switch Receiver

    You said you lost all of your remote controls for your garage door opener. So, If this is an existing garage door opener, post a picture of its control board so we can see the wiring. The picture you posted doesn't have any wires going to it.

    Connect Switch Receiver

    Most garage door openers have a remote push button to open/close door mounted inside the garage. I would guess the relay contacts (com,no) would need to be (parallel) spliced at the point where that push button needs to terminate. Read the garage door manual.

    Dont want to blow up my welder.

    The welder is a horrible load because it's essentially a short circuit every time you strike an arc. I agree with duke37 that you need upwards of 5kw. It's doubtful 16amps is enough. I wouldn't chance it. I would go with at least 7kw. I don't see it being less expensive using an alternator...

    Braun Shaver 7526 Circuit Board

    Very good, I admire your stubbornness. Something happened to that resistor to make it end up in pieces like that. Take a close look at the blob of solder on the right side of it. It shouldn't make contact with both traces. That could be your short while the diode may still be fine. You could...

    Braun Shaver 7526 Circuit Board

    Not if a part is missing. Did that resistor explode or did you try and solder it and it melted? It looks like solder shorted the two traces on the right side. That could cause your overheating batteries. There is a link to suppliers on this forum. I'd start by removing all that solder around...

    Unidentified Circuit

    ...Better yet, grind off the resin with a belt sander so we can see components. Perhaps it's some kind of filter network?

    How to assemble a DC gear motor with encoder

    The encoder doesn't have to be attached to the motor itself, it can be attached to the linkage somewhere or the wheel itself. Sometimes adding a rubber wheel and a spring to the encoder shaft is all it takes to get acute feedback. Similar to how an rpm meter is used. It might be better (more...

    In my state you must also have a valid Fire Alarm Specialist license to work on its related wiring, and if you are a contractor, you must hold a Fire Alarm Contractor license. As well as being insured and bonded.

    I'd be glad to help you figure it out. I merely asked if you're qualified.

    If someone doesn't know how to wire a damn switch they have no business fiddling with a fire alarm panel. This is something that impacts life safety so it's entirely relevant. I'd rather you feel insulted as opposed to a building burn down taking innocent lives.

    No offense, but I'd expect a fire alarm specialist to know this. Are you qualified to work on fire alarm panels?

    Aquarium DIY Project - need help identifying a component

    Yes, automatic. Basically household 120v powers the relay coil. The coil magnetic field pulls the normally open contacts closed to deliver power out to pump during normal use. Once power is lost, the coils magnetic field collapses and a spring pulls contacts back to the normally closed position...

    Aquarium DIY Project - need help identifying a component

    You need it to have contacts that are capable of handling the inverter ratings even if you are only using a few watts. The Ac to aquarium past the relay and the Ac out of the inverter can be bridged together as one but run a neutral (grounded conductor) along with it. The push button latches the...
