If my miner goes offline for any reason (in the recent example offline for 5 hours due to failed surge protector).

Is there a ramp backup delay to get back to full force? I believe I read a new miner takes 7 ish days.

On a related note I have a S9 powered by a EVGA SuperNOVA 1600 P2 80+ PLATINUM. Do I need to run a surge protect between it the power supply and the wall outlet? Shouldn't the fuse in the fuse box just trip if there is a surge?
