: Okay, here's the deal.

: As it turns out, three 30 Amp circuit breakers in parrallel will trip before the one 60 Amp fuse. This fact was experimentally determined using a big power supply and an even bigger potentiometer ;-).

: So, knowing this fact, you can build from legal kit materials a device that can be put in series with the 60 Amp fuse that has the purpose of protecting the 60 Amp fuse.


The device is constructed from legal kit materials, but is using them in this manner legal?

Rule C5 states that 'Electrical devices may only be wired as described in Section 2
and/or the Robot Rules.

The wiring diagram in section 2 does not show two or more 30 amp breakers wired
in parallel connected to a single device.

Rule C15 states 'ONE [emphasis mine] 30A circuit breaker (provided in the Kit)
must be installed in series with each speed controller on the +12 Vdc input.
