This is the same technology as used in the EXP2BUS. It's what attracted me to that device and it seems to work well. I have had an occasion where one circuit has tripped and reset itself after having been unloaded for a few seconds. Of course that doesn't remove the necessity to find out why the circuit tripped in the first place, and in general circuit boards tend to need to stay cleaner, and cooler than circuit breakers and switches. I found the price was about the same, when you compare the cost of ten or so circuit breakers and ten switches etc. to the bare board version.

But I'd have to say that, to do it all again, I'd go with a vanilla version of one of Mr. Nuckolls designs, with circuit breakers and switches.
