Thank's X that's what I needed to know , filed away for future reference for my first mech .I don't use a safe fuse because they don't allow the sub-ohms I occasionally build. Those fuses are a good safety measure, but I believe they trigger somewhere between 6 and 8 amps. My 0.4 dual coils draw over 10 amps, so a fuse is moot. Knowledge and good batteries are the best thing to prevent hazards. Today's 30 amp bats are a better safety measure than any fuse.
