The electronic Control Center of the system, our Transfer Switches, powered by Briggs & Stratton, go well beyond the management of the transition from utlity service to your Home Generator System when the power goes out. These full-featured switches also include patented power management technologies that manage the power demands of up to two, 5-ton central air conditioners while protecting against power overload.
Automatic System Features
- Fully Automatic – All Milbank transfer switches monitor utility and generator voltages and will automatically connect to the appropriate source of power. 100 and 200 amp switches are capable of “whole house” power transfer in residential/small business applications.
- AC Power Control Module™ – When the power goes out, most people think they have to go without central air conditioning to weather the storm. Keep your cool with patented computer-controlled transfer switches featuring the AC Power Control Module that manages up to two central air conditioners while safeguarding against power overload. The size of your generator dictates the level of comfort provided by this feature. 12kW – One 4-Ton AC, 15kW – Two 4-Ton ACs, 20kW – Two 5-Ton ACs.
- Exclusive Design – Each transfer switch is UL approved, custom-made and dedicated exclusively for Milbank, reducing overall cost and giving you exactly what you need for your home or small business.
- Supervisory Control – This industrial-grade component features a control panel with red and green LED lights indicating the power sources available, and two relay-operated contacts that allow the user to manage external loads during a power outage.
- Lightweight/Ease of Installation – Efficient component selection has resulted in switch gear optimization for a lightweight product solution to residential/small business installations. Five wires – three 120/240 VAC and two utility supply wires (for battery charger and optional battery warmer and oil heater) also allow for efficient one-person installation.
- Computer Friendly – All transfer switches feature Automatic Voltage Regulation to ensure a safe and stable sine wave to sensitive electronics.
- EEPROM (Electronic Program Read Only Memory) – All transfer switches feature non-volatile memory, so when the power goes out, the transfer switch “remembers” its programming once power is restored. The switch never has to be programmed or reprogrammed once it is installed.
- Variable Engine Warm-Up – All of our switches feature 20/50 second warm-up options: 20 seconds for warm weather starts or a 50 second setting when the generator requires additional start time in colder climates.
- Safety Features – All transfer switches are solenoid-operated from utility or generator inputs and contain electrical interlock switches to eliminate the possibility of dangerous back-feed to a line during an outage.

How to Select the Ideal Automatic Transfer Switch
Once you’ve selected a generator, selecting an automatic transfer switch requires that you focus on two things:
- Service Amps: Milbank automatic transfer switches come in two sizes: 100 amps and 200 amps. To determine your needs, first take a look at the main breaker on your distribution panel. If you have a 200 amp main breaker (which is common in new homes), you will need a 200 amp WHOLE HOUSE automatic transfer switch. If you have a 100 amp main breaker (which is common in older homes), you will need a 100 amp WHOLE HOUSE automatic transfer switch.
- Installation: Once you have selected a switch, there are basically two ways to install an automatic transfer switch:
Standard Installation: The most common option is to install it inside the home next to the main distribution panel. Your electrician will also need to install a sub-panel to manage the load properly.
Service Disconnect: Milbank also offers automatic transfer switches with “service entrance disconnect.” These outdoor transfer switches are connected directly to your home’s utility meter instead of the main circuit panel. The service disconnect option eliminates the need for the sub-panel.
How It Works
Home Generator Systems feature a continuous fuel supply from either Natural Gas or Liquid Propane and are permanently connected via a transfer switch to your home’s electrical system for an automatic response to power failure.
- The Home Generator System’s computer-controlled Transfer Switch continually monitors your connection to local utility power.
- When utility power is disrupted, the transfer switch confirms that a true power outage has occurred and signals the standby generator to start.
- The system supplies backup power to your home within 30 seconds. When utility power is restored, the system automatically senses it, restores utility power, and resumes monitoring until the next utility failure.
