The failure to automatically transfer a building’s electrical load to an emergency generator is a nerve-racking scenario that any facility manager would prefer to avoid. For this reason, automatic transfer switches (ATS) are considered one of the most critical components of an emergency power system. This article discusses the use of “open vs. enclosed” contacts in transfer switches, and also alerts you to a basic transfer switch design feature that may not be in your current specifications, with possible negative consequences for the facility’s owner.
Should you include a day tank in your emergency generator fuel supply system? The answer to this question requires an understanding of the applicable code, some technical information on the proposed engine, and some basic piping calculations. Follow the steps outlined in this article to insure a reliable fuel supply system for your emergency generator.
You mean well, of course you do! You dedicate your education and experience to create practical and reliable designs for your clients. But, when it comes to specialty areas such as fuel system design, researching new codes and technologies can be a big challenge, especially while trying to meet fast-approaching project deadlines. So, is it inevitable that some design flaws will find their way to the final construction documents? Well, don’t give up just yet!
If you do design work for commercial facilities, chances are that the architect for your last project gave you very limited space for mechanical and electrical equipment rooms. When specifying equipment such as emergency generators, the equipment footprint is always important. But, what about overhead space for things like the engine’s exhaust system? What are the options when the room’s height appears insufficient?
