Safety primary concern with batteries.

Safety has got to be a primary concern whenever you are working with batteries. Even though they are low voltage, an arc across the positive and negative terminals of a battery can be extremely dangerous and can destroy the battery. Looking at an alternating current (AC) sine, we can see that voltage delivery comes in waves. These rapid pulses of power range in voltage from zero to whatever the peak voltage is in the given system. When AC voltage reaches zero it gives your muscles a brief but repeated life saving chance to relax and release in the event of electric shock. Direct current (DC) power doesn’t want to let go of you like alternating current (AC) power. DC voltage remains consistent in its delivery, making it very dangerous stuff, especially at higher voltages. Be aware and respectful of the electrical dangers involved with batteries and electricity at all times. This should be common sense, but always disconnect the battery bank from all sources of charging and discharging before working on them. When installing a new battery bank draw a diagram before you wire, this could greatly reduce the possibility of making a simple mistake. Minimize your chances of getting zapped by using taped or insulated tools and remove all jewelry and metal watches. Also, tape the loose ends of cable that you’re working on, thick battery cables seem to flop around just looking for trouble. We like to use Class T 400A fuses connected directly to the positive terminal of a battery string, so no matter what else is going on in the system, we know that our batteries are fused. I know… fuses and disconnects can be annoying and expensive, but they are required by code and more importantly they might save your life, so use them. If you aren’t sure what size fuses or which disconnects to use in your system, call us or your local product supplier and we’d be glad to help.
