Progressively turns your circuit breakers on so they don't trip

This log continues this one: 3. Dimensions

The main idea of the project is not sequencing, but the shape and dimensions of the circuits that gets directly screwed in the circuit breakers. Here is the top view of a typical circuit breaker, with a perspective of the jaw that usually grips on copper wire:

The inputs are shifted to ease wiring, in particular with plain, straight copper busbars, such as the one shown in the initial project page's avatar:

The idea being that one busbar will connect all the circuit breakers in the back of the box, and the front busbar is replaced by a PCB with the SSRs and electronic circuits.

As mentioned in the previous log, the width is 18mm, the standard of the industry:

The claw/jaw is approximately 5mm wide but it's better to create a 4mm wide tip.

The sequencer's supply can be provided to the boards with a sort of thin flat metal wire that will also be screwed in the back receptacle.
