myElectricPlan and FusePlan both plan outlets and the board in the browser. Price, free limits, account, parts and who each suits, as of October 2026.
Panelworks and FusePlan both put real breakers on a DIN rail in the browser. Price, account, parts, outputs and who each one suits, as of October 2026.
Plan an electrical renovation for free: draw your rooms, place outlets in the DIN 18015-3 zones, group circuits and hand your electrician a PDF.
From AC to B+: what separates the six RCD types and when type B stops being enough.
What actually separates B, C and D breakers: the magnetic trip threshold, not overload protection. With a trip curve and some of the math behind it.
RCBOs save space on the rail but cost a lot more than a separate RCD and breakers. A look at both sides, with the ABB DS301C as an example.
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 a fuse box rarely fits on the first try without real module widths and how FusePlan catches that before you touch a rail.
Why ferrules come in 10, 12 and 18 mm lengths and what separates a good one from a no-name bag.
