Installation Notes

Battery clamps of this type are installed by electricians and marine technicians performing battery service or temporary power connections. Always disconnect the negative terminal first and reconnect it last to reduce arc and short-circuit risk. Ensure jaw contact surfaces are free of corrosion before clamping to maximize conductivity. Follow applicable NEC and ABYC guidelines when making connections in automotive or marine electrical systems.
