Fuse & Breaker Sizing
Watts don't pick fuses — amps do. Choose your system voltage:
PLEASE NOTE: these amps are grid-based — please change to match your system voltage below. A 12V setup draws roughly 20× the amps for the same watts.
Peak load (simultaneous)
0.0A
Main fuse / breaker
5A
Main fuse = peak amps × 1.25 safety margin, rounded up to a standard size. It protects the cable — size the cable for the fuse, never the other way round.
What does my fuse allow?
My fuse isA= 3,450W max
at 230V. Any single load above that blows it — and keep continuous loads under 80% (2,760W) for fuse longevity.
