Yes by your definition you can call all sorts of things current limiting devices. A light switch can be a current limiting device. Lots of things will, by your definition "limit" current if you define limit as stopping all current. That does not change the fact that the standard usage for that term is for a device that limits how much current flows in a circuit and to use that terminology, not a device that interrupts current completely.

If this is so critical and distracting to the discussion feel free to focus on more important matters and drop the subject any time you like.

Please note it is not just my "preferred wording", it is the wording used in the industry and the wording used in electrical engineering. I seem to recall at least one other person on this thread called you on that issue as well.

Remember, I walked away from responding to you in this thread and said you could have the last word. You directly addressed me in a post to bring me back into it.

Using fuses or breakers for current limiting is not precise as that is not their main purpose. For example a 20 amp Blue Seas breaker will not open until about 26 amps of current pass through it continually. This is stated on the breaker. Fuses are even less accurate as for example an ANL fuse will pass approximately 150% of rating under load before blowing. This varies a bit with each fuse size. In both cases the breaker will open and the fuse will blow almost immediately in the case of a short circuit. That is the main purpose of a breaker or fuse.

The best solution is not to try to limit current in the case of charging but to wire for the results as far as cable size is concerned.

Please, focus on the important matters, all devices have certain tolerances including solid state
ones.

A fuse or breaker clearly falls within the definition of a current limiting device. What does a fuse limit? Current. Period. I can't even believe this is being challenged.

Let it go already, Rod! You sound like you're arguing just for the sake of arguing. You made your point, time to move on...

Maybe your right, because I feel compelled to advise that the quotation in your signature was not actually made by Mark Twain.

Seriously, I have devoted significant time and effort to this thread,
providing sound advise, challenging gross errors, and suggesting valid ideas and alternatives. I get quite offended when the terminology nazis come out and attempt to detract from it. If the terminology I used was wrong or potentially misleading, I would be the first one to admit it for the purpose of clarity and avoiding confusion. Moving on.
