Hello Kevin,
I believe you need to look into your end-product standard for the exact
requirement.

To expand on Ted's post, think

Quick question to the US requirements experts.
If I want to get a product I am developing UL approved but a circuit breaker
I plan to use is not UL listed?
I can get a CB Certificate and test report for the breaker. If I have that
can I get UL approval for my device even though the breaker is
Hi Don:
Fuse the power to 15 watts for each supply to each peripheral.
