The Busbar mark reads as a busbar first, an isolated conductor bar feeding three non-contact circuits with terminal nodes, and resolves into a B on second look. There is no wordmark: the symbol carries the identity on its own.

The marks

Primary Slate disc, lime mark. The default. SVG PNG

Inverse White disc, slate mark. Dark backgrounds and photos. SVG PNG

Glyph, lime Mark only, no disc. Inline and one-colour use. SVG PNG

Glyph, slate Mark only, for light surfaces. SVG PNG

The primary mark is also available at 1024px, and there is a bolder favicon cut for 32px and below.

Charcoal #1E293B Secondary surface

Using them

Default to primary on light or neutral backgrounds; use inverse on dark ones and over photographs.
Use the glyph, which has no disc, for inline text, READMEs, terminals, and anywhere printing is one colour.
Switch to the favicon cut at 32px and below. Minimum size is 16px in any form.
Keep clear space around the mark of at least 25% of its diameter.
Do not recolour, rotate, stretch, add effects to, or rebuild the mark. Scale the SVG instead.
