Question 3: The IR receiver circuit must be protected by a 20-amp circuit breaker (see Rule <R55>). .......

I'm not sure how to interpret that. If you use the +5v from the RC, the IR receiver IS protected by a 20-amp circuit breaker... (since the RC is powered through a 20-amp breaker).

In the past they specifically have allowed sensors and custom circuits to be powered by the RC's 5v rail. I don't know why that would be any different this year?
