I believe this is only legal on the spike running the compressor -

<R61> The control system is provided to allow wireless control of the robots. The Operator Interface, Robot
Controller, Speed Controllers, Relay Modules, Radio Modems, Batteries, Battery Charger, AC Adapter, and
9-pin cables may not be tampered with, modified, or adjusted in any way, (tampering includes drilling,
cutting, machining, gluing, rewiring, etc.) with the following exceptions:
• The dip switches on the Operator Interface may be set as appropriate.
• The user programmable code in the Robot Controller may be customized.
© FIRST 2006 FIRST Robotics Competition Manual, Section 5 – The Robot, Rev C Page 18 of 30
• The Speed Controllers may be calibrated as described in owner's manuals.
• The fuse on the Spike relay for the Air Compressor may be replaced with a 20 Amp Snap-Action circuit
breaker.

But if you have to worry about the globe blowing the fuse, then you have a mechanical design problem (stalling the motor).
