    Disagreeing with a Youtuber - DC Breaker Safety Concerns

    Oh cool. You have an interesting job then. I work with explosion proof nat gas stuff overall myself. We recently finished our intertek training. I'm a bit new to this world of certifications lol. But anyways, man. I feel bad for if somebody sticks a "breaker" like that in their basement and it...

    Disagreeing with a Youtuber - DC Breaker Safety Concerns

    Good evening, I recently watched a couple minutes of a popular youtuber named David Poz advertise an affordable, unknown brand 100+ Amp DC circuit breaker. In the video he mentioned the breaker was UL listed. I was highly skeptical of the price and quality, so I searched for it online. I work...

    Our NEW GO-TO LiFePO4 vendor...09.20.21

    Yo. It looks like DOCAN sells a cheap 100 Ah 12V battery. Wonder if this might be an interesting future Will Prowse review since he's reviewed several already. Does Will do Alibaba reviews...

    Do fuses work at all?

    Fair point. Hopefully that brand of block permits him to properly torque-sandwich the direct cable-to-fuse connection.

    Do fuses work at all?

    Whoops. Totally went past that. Yep. I bet that fuse block has a nasty contact resistance. Massive red flag to me. If OP’s connections are okay otherwise and gets an Eaton/Bussman fuse holder, the problem might go away.

    Do fuses work at all?

    Do you have a picture or a link to your fuse holder? Are you fuse holder terminals clean?

    Thread titles too often not valid - like "HELP!" or "Information Please"

    On a very similar note, have the mods considered manually re-titling ambiguous thread titles as one comes across them? For example, on bogleheads.org (a finance website I frequent), when a poster creates something ambiguous like: "Help - SO MAD", an admin would re-title the thread with an...

    source for 120v efficient refrigerators

    I just moved from a small rental apartment into a rental house in central Midwest. I don’t use a lot of electricity. My electric bill went from $90+ a month to $40+ (for the same season months) mainly due to the change from an old 90s fridge to a 2021 fridge. The one we have is a very basic...

    My 280ah CamperVan system

    Interesting; thanks for your insight boboxx. I guess if your beer is cold, your battery compartment hasn’t melted, and you don’t have a long rant post about the supplier, I should be good to order some myself. 👍
