Re: IR Beam Breaking Circuit

By R47, he could (should) have required you to replace the wire with a 18 AWG wire or larger. You did not specify the wire size you used, but it would be reasonable to use an in-line fuse if the value of the fuse was selected to be appropriate for the wire size, and was chosen to be a "fast blow" type fuse. Situation becomes ambiguous though, unless you can provide documentation about the device and it's load characteristics.
