Hello, all, and a fuse question for a practicing electrician (or anyone in the know):
Assuming a residential branch circuit is fused for 125 volts, 30 amps and the fuse box accepts the rejection base ("S") fuse, how interchangeable are the 30 amp "D" dual element time delay (has the spring loading) and the 30 amp "SL" time delay types? Thanks for your time and comment. Sincerely,
