As the Chief Inspector for FIRST, I STRONGLY encourage that someone address this via Q&A. I could give you my interpretation and whether I would allow multiple Spikes on the same breaker but my preference is to make this "official" by using the Q&A.

Also, I didn't sense any interpretations in Al's response. I don't think that he explicitly stated whether he would allow or disallow multiple Spikes per breaker. He did, however, state something very important - trying to actuate a pair of 20A Spikes simultaneously on a single 20A breaker (as an example) is asking for "failure" (ie an open breaker) and should be avoided based on solid engineering principles. IF multiple Spikes per breaker are allowed, 18AWG wire must certainly be used everywhere (per rule <R47> with a single exemption for pneumatic valves).
