Release notes and updates on FusePlan, plus posts on electrical engineering topics.
Crimping Twin Ferrules: 10 and 16 mm²
Why a standard ferrule tool gives up on twin ferrules at 10 mm² and up and how to crimp 10 and 16 mm² TWIN cross-sections cleanly anyway.

Why I built FusePlan
Why a fuse box rarely fits on the first try without real module widths and how FusePlan catches that before you touch a rail.
Wire ferrules: choosing length and quality
Why ferrules come in 10, 12 and 18 mm lengths and what separates a good one from a no-name bag.
