MainsKeeper — Feeder Board
01Primary lockup · wordmarklockup.svg · wordmark.svg
Dashed outline = minimum clear space: one feeder-bar thickness (6 grid units) on every side. Minimum lockup width 120 px; below that, use the mark alone.
02Logomark · construction
Every edge sits on the 3-unit half-grid; the mark is built only from rectangles, so it renders flat and snaps cleanly to pixels.
03App icon · favicon
The 512 icon adds a tick rule along its base. The 32 and 16 px files are hand-fitted redraws, not scaled copies: bars snap to whole pixels and the breaker gap is held open at 2 px (16) and 3 px (32) so the keeper node never merges into the tap.

One colour: the keeper node keeps its shape, so the mark still reads with no yellow. Use for etching, rubber stamps, fax-grade printouts and equipment labels.

Status is always colour + glyph shape + word. Colour is the fastest cue on the board, never the only one.

Mains Keeper
09The idea
Every site is a feeder on one board. The mark is a one-line diagram: two bus bars and a top feeder draw the M; two inner feeders step toward a centre bus tap; the tap stops short — a breaker gap — above a yellow keeper node. The keeper sits on the line and watches. It does not close the gap.
That gap is the product promise: MainsKeeper observes power and contact, and never switches, shuts down or commands anything.
Why not a bolt in a shield
A bolt says “electricity” and a shield says “protection”. MainsKeeper gives no protection, it gives certainty about what it has seen. A shield would promise something the product will never do. The feeder board instead borrows from utility dispatch, where operators read one-lines and annunciators, not badges.
- R1Flat fills only. No gradients, glows, bevels or lighting.
- R2Yellow belongs to the keeper node, warnings and focus — never decoration.
- R3Below 24 px use the hand-fitted favicon files.
