ASCO Power Transfer Switch Products in California
At Leddy Power Systems, INC., we ensure any equipment we offer is top-of-the-line, which is why we endorse ASCO Power Products. As innovative leaders in the field of energy technology since 1888, they patented the first commercially available automatic power switch in 1920. Over the years, they’ve continued to improve their designs and expand their offerings. We are proud to offer ASCO Power Transfer Switch Products to a variety of energy infrastructures in California, such as:
- Commercial Buildings
- Data Centers
- Emergency Standby Power applications
- Facilities Maintenance Managers & Chief Engineers
- Government Buildings
- High Rise Buildings
- Hospitals & Healthcare Facilities
- Large, industrial diesel generators
- Manufacturing and Processing Plants
- Military Bases
- Prime Power applications
- Public Utility Power Companies
- Specifying Electrical Engineers
- Waste Water Plants
The full list is a lot bigger, but you get the idea – ASCO Power Products are not only good, but integral to power array setups across the globe. Let’s take a look at some of the products that they provide, just to give you an idea of how far they’ve come from that first humble automatic transfer switch!




Early transfer switches were fairly limited, typically relying on current measurements to determine when to switch on a secondary power source as backup. These days, however, they’re a whole different animal and ASCO makes some of the best!
ASCO Automatic transfer switches feature a unique solenoid operator which is there in order to lock and force primary contacts closed on high current faults. This ensures that they don’t open, much the same way that a circuit breaker would, and helps to ensure that power redundancy strategies are going to kick in like clockwork when they’re needed.
Listed to UL 1008, ASCO Automatic Transfer Switches will work with pretty much any generator out there, so transferring loads from utility to backup supplies is a piece of cake.
In more complicated environments, you’re not looking at just one main power supply and one backup, but rather a more complex setup with redundancies to ensure that things like server racks, refrigeration units, and other critical environmental variables that need constant power are going to get it.
Some environments also need scaling, so that two or more power sources may be tapped when energy needs are higher than anticipated.
That’s where products like ASCO Paralleling Switchgear come into play. Allowing you to perform operations such as scaling capacity and create redundancies, ASCO’s paralleling switchgear gives you more granular control on your power to ensure that it’s always consistent and getting where it needs to go.
Critical Power Management Appliances
Complex power requirements call for management solutions, and ASCO Critical Power Management Appliances are among the best on the market today, providing users with real-time information from critical parts of their power network. This is done by incorporating meters, gateways, and annunciators to measure and monitor power flow, and by translating this information using ASCO’s proprietary power management software. The result? Transfer switches, load banks, generators, and even multiple buildings and associated applications – all in ASCO’s centralized management solution.
