individual slip rings rated at 10amps run in parallel

Yes Ren I would guess so

But hope to hear from others with more thorough knowledge of power apps

In parallel you can add current rating (amps) so 8 slip rings each rated 10 amps can, in total, carry 80 amps. But don't forget: starting current, reactive power, stuff like that, and an (I think) quite important question: what are you doing trying to set up heavy-duty industrial type electrical plant when you don't know enough to answer very simple basic questions about it and think someone on a forum can save you all that money a real electrician would cost?

I see fires, shocks, death, injury, lawsuits, prosecutions in your future.

Almost everyday Con we encounter several postings very similar in comprehension of electrical or mechanical and I do wonder the reason: Is it maybe that youth and esl go together

At any rate we can't suppose many such queries result in lawsuit or death. Let's give 'em credit at least for asking first

Sets me to wondering whether there might in fact be some sort of advantage in the parallel arrangement

We don't know if the OP is an ESL learner. What we do know is that he or she is apparently responsible for commissioning heavy-duty industrial type electrical plant, yet has to go on a web forum (and not even an electrical one!) to ask a basic, beginner-level question that a person in such a role ought not to need to ask. One wonders what other areas exist that he will be operating in where lack of knowledge/experience could lead to elementary mistakes that could lead to overloads, burnouts, code/safety law breaches, voiding of insurance, etc.

Possibly the OP is from a country where regulation is lax or nonexistent. I suspect this about a lot of this type of post.

Yea Con quite possibility. Wonder too if some of these might also censor or prohibit activities such as ours here

He hasn't said if his three phase power source is 80 amps per phase, in which he will need all 24 slip rings if they are rated at 10 amps each. If so, his lack of such an elementary level of understanding is kind of scary.

Alas Con I probably would have made the same slip
