I purchased a dust collector from Harbor freight that works great when attached to the wall outlet, but when I attached it to an Opto22 relay to be controlled programmatically it blew the 30A fuse on the 120v side of the Opto22 that I had placed in-line. The specs for the dust collector show it as 20A and when plugged into my wall outlet which has a 20A breaker it never trips it....
Soo my guess is it had to do with startup surge or something like that that the fuse cannot handle but the breaker can. My question is if it would be okay to just remove my inline fuse and rely solely on the breaker for protection? Could my opto22 handle the startup surge without damage? (it is a 25A relay which is higher than the breaker) should I just try to get a slow burning fuse instead?
Just curious what my options are. Thanks.
