Pro/Tran by Reliance Controls
Latest technology in load-side transfer switches...
with built-in analog meter
high capacity 30A 2pole branch
interchangeable breakers


This is the most advanced load-side transfer switch available at this time.  This NEW Q-series Pro/Tran switch from Reliance Controls has all the great features of the original plus some new capabilities...

* Analog meters for indicating the power on each hot leg of generator.
* Includes (1) 30 amp double pole branch circuit breaker - allows you to power
   that 240Vac electric water heater or other large load.
* Designed for standard 1" plug-on interchangeable circuit breakers.  Allows for
   changing breaker sizes in the field using readily available breakers.
* All branch wiring (except for 30 amp circuit) sized for 20 amps so that any
   15 amp breaker can be upsized to 20 amps in field.

Easy to install and operate, connects portable generator to residential load center.  Allows manual transfer of individual loads to prevent overloading generator.   Each individual circuit can be transferred separately and only as needed.   Now required by Article 702.6 of the 2002 National Electric Code to prevent inadvertent backfeeding of electric power from generator into utility system which can be a safety hazard.
