small breakout panel?

bmetbmet Solar Expert Posts: 630 ✭✭
What would anyone suggest for a small-scale breakout panel? I'd like to be able to add connections for future upgrades(DC lighting, vent fan) and I don't look forward to adding ring after ring terminal to my battery posts. Thank You.

    I'm not sure what you are describing as a break out panel. If you buy a Square D QO series panel, you can get them in a number of breaker spaces and amp ratings. QO breakers are DC rated to 48 vdc. Then you can use one fuse at the battery, one run to the lug in the panel, then branch circuits as needed.

    Is that wht you have in mind?

    PS They are available at most big box stores.

    The other is Fuse arrays (from Marine stores if you want higher quality stuff) and bus bars (for return connections) is much more cost effective.

    Prime Products (not expensive)

    You might also look at the "RigRunner" products here:

    This system uses ATC/ATO fuses, and is primarily for 12 VDC, altho, the fuses may be rated for 24 VDC.

    Thank you for the reference. I went to Home Depot and Lowes, all of the SquareD breakers there are AC. Didn't see anything for DC. I want to have a panel which I can access without having to disconnect the battery to add another circuit. It would also make things easier for future upgrades.

    Look carefully at the Square D QO breakers. It is possible that home depot is now only carrying the home owners line of cheaper breakers. QO are DC rated to 48 vdc

    The home line series of Square D have an aluminum buss rather than the better tin buss. QO s run ~ $8

    PS. find a wholesale electrical house who stocks Square D. Most will sell over the road if you walk in and act like you know what you are doing,, "I need a SD 4 space load center and 3 Q0 breakers please"

    As mentioned already, Blue Sea makes some very nice DC fuse blocks. Multiple circuits, various configurations. I'm using one of these also.

    For a larger setup, Iota makes a nice DC distribution panel. Many more circuits, each with a separate blade fuse, and an LED that will illuminate when the fuse blows (great for troubleshooting).

    Here's details about the panel:

    Front, with no fuses installed.

    Thank you for the reference. Those look compact and simple. I'd love to have a about 4 or 5 open circuits for small stuff, but I wonder if the 40 Amp total capacity is sufficient?

    The fuse block is kind of the picture I originally had in mind, but Blue Sea really makes it clean and sleek. Thanks for a look at both ends.
