Just because the battery-supplied systems on cruising boats are low voltage, that does not make them safe, and yet that's the common view.
Sure, none of the DC voltages on our boats (12, 24 or 48) will hurt us—except possibly the last, and then only in special circumstances (don't stick a 48-volt wire in your mouth)—but the current (amperage) sure can¹.
So let's take a look at five ways we can reduce the chances of getting hurt. Particularly relevant since we just published several articles encouraging members to work on your own systems and have more coming².
¹Actually, it's always the current that damages people, even in high voltage (shore power) systems, but let's not split the hair in four.
²If this sounds like an article written to cover my ass and keep our journalism insurance underwriters happy, trust your instincts. Nonetheless, these tips reduce, but do not eliminate, very real risks.
