Re: Jaguars with 20 Amps?
The FP motor must run through a 40 amp breaker.
Window motors may run through a 20 amp breaker. |

Re: Jaguars with 20 Amps?
can you please address me to the source of this info in the manual? We've been searching for that...

Re: Jaguars with 20 Amps?
Quote:
<R39> All active PD Board branch circuits shall be protected from overload with an appropriate value auto resetting Snap Action circuit breaker (from the KOP or identical equivalent). A. Each speed controller branch circuit must be protected by one and only one 20-amp, 30-amp, or 40-amp circuit breaker on the PD Board. No other electrical load can be connected to the breaker supplying this circuit. which isn't really helping at all ![]() |

Re: Jaguars with 20 Amps?
The breaker size depends on the wire size not the motor. Cims draw lots of amps which requires 12 awg or larger wire. Wire of that gauge can use the 40 amp breaker. Window motors use around 21 amps which means it can use smaller wire and breakers. If you wanted to wire every motor with 10 awg wire. There isn't a rule that says you cant use the 40 amp breakers for all the motors!

On a related tangent, note that <R48 A> requires that the Fisher-Price motor be powered by a Jaguar or Victor 884, but the window motors can also be powered by Spike relays. |

Re: Jaguars with 20 Amps?
There is no rule that specifies a breaker size for a motor.
The rules do require that CIM and FP motors must be controlled by a speed controller. Any legal motor can be controlled by a speed controller if variable speed and direction is needed for you application. CIM motors can be driven by a 20 amp circuit breaker if a team so wishes. However, the CIM motor may not provide the performance and the breaker will likely reset regularly producing a lot of heat in the breaker. |

Re: Jaguars with 20 Amps?
Sorry - I was quoting an outdated (2010) rule.

But a good practice!
