Thiamin, vitamin B1, works in the form of a co-enzyme (enzyme helper) in reactions that produce energy in our bodies. It helps break down glucose (a simple sugar) for energy in 2 steps of metabolism; helps make DNA and RNA and produce energy-rich molecules that power protein synthesis.

CAFI - Combination Arc-Fault Circuit Breakers (protection against over loads, short circuit, parallel arcing, and series arcing) Breakers with CAFI suffix provide standard thermal/magnetic protection, PLUS protection against heat damage caused by parallel AND SERIES arcing in the circuit.
