Here's another PCB:

I figured we could have a relay board in our modular power system, and
my PCB layout guy had time, so I did one.
 
Then I figured that instead of fuses to protect the contacts and PCB
traces, I could use Hall sensors and drop out a relay if the current
exceeds 8 amps. Then I figured I may as well report the currents to
users. And why not voltage too? Then  it became a programmable circuit
breaker module. With average and RMS voltage and current and power
measurement and waveforms.  And programmable ganging. And plugin fuses
for bussing. Somebody stop me.
