Agreeing with everything here. Applying even a small reverse voltage to an electrolytic, or a tantalum cap, for that matter, can make it blow.

Even if you're well-versed in electronics, I recommend asking an electrical mentor to sanity-check your connections before hitting that main breaker,
especially if it's an expensive component (like an Axis camera or a router (I may or may not be speaking from experience here)).
