Rewired an old florescent tube fixture for LED with a ballast delete

You should be able to get those at any automotive store. I’ve seen them at ACE too.

Yeah, I thought about automotive fuses but I wasn’t 100% sure whether they’d be suitable for AC power. These ones definitely are

Fuses are thermal devices. They don’t care if it’s AC or DC. It’s basically the weakest link in the chain. It’s supposed to fail WAY before anything more important (or expensive) fails.

They don’t care if it’s AC or DC

I figured this was most likely the case, glad to have it confirmed. I just wanted to err on the side of caution

Fuses do care about AC or DC as AC will self quench the arc while DC will not. DC ratings on fuses are lower than AC for an equivalent fuse. Always read the documentation.

Nothing wrong with that.

You can never be too careful when trying to tame the magic smoke demon.

Caution: fuses, breakers, resistors, and quite frankly, all electric or electronic components, have a voltage rating. A 12vdc automotive fuse is not built with sufficient clearance or creepage to guarantee that 120vac or 230vac won’t accidentally conduct to the wrong places.

A quick look at high-voltage fuses up on a utility pole reveals that they are indeed built larger for higher voltage. OP is correct to be concerned, but because of voltage, not necessarily because of AC or DC.
