What are the advantages/ disadvantages of using a manual transfer switch versa an automatic transfer switch?
Advantages:
• Significantly lower cost
• Smaller size
• No maintenance required for the generator
Disadvantages:
• Longer time before generator power is established
Can an operator backfeed the utility gird and cause injury to themselves without the use of a StormSwitch™?
Accidentally backfeeding the utility grid is a very dangerous situation. There are other methods and products available for powering up from a portable generator. However, the StormSwitch™ is the only product available that combines the simplicity of cam connections with a safety interlock device that prevents backfeeding the utility grid.
Can the StormSwitch™ be tampered with when not in use?
Once installed, the device is always in use. The StormSwitch™ door can be padlocked, preventing unauthorized entry. The disconnect handles can be padlocked in the “OFF” position for further security. With a minor modification, the disconnect handles can also be padlocked in the “ON” position, however, this is not recommended. For complete security a separate, factory or field installed kit is available which is a padlock able, hinged covers that installs over the handles.
How do I know what model will best work with my specific needs?
ESL’s knowledgeable Sales personnel will gladly assist with helping to identify the proper switch for your application. The key factors will be the voltage system and the desired emergency load that is to be fed.
What is the reason an additional circuit breaker is available with the purchase of a StormSwitch™?
Circuit breakers provide over current protection, switches do not. If the supplied generator does not have built in over current protection, then it is recommended that the generator disconnect and the StormSwitch™ be equipped with a circuit breaker rather than a switch. Also depending on your specific application, you may or may not need over current protection on the utility side. Again, ESL’s knowledgeable Sales personnel will gladly help you in deciding what combination works best for your application.
Do the generators have the same color coded plugs that the StormSwitch™ does?
ESL cannot guarantee that. Industry standard is green for ground, white for neutral, and typically black for “A” phase, red for “B” phase and blue for “C” phase. When entering in an agreement for generator service, it is recommended that you request the aforementioned color-coding for the cams.
After the StormSwitch™ is installed by a licensed electrician, what type of basic training is required for use?
Minimal. The key is to arrange for the generator to arrive with 400-amp rated, single pole, cam style, female plugs. Then simply connect the plugs to their corresponding colored receptacle in the StormSwitch™ following the directions on the unit.
Does the StormSwitch™ have any features that will protect it from any environmental factors or animal intrusion?
The StormSwitch™ is a type 3R enclosure. This means it is suitable for outdoors and will protect components from rain. To insure that insects, debris, small animals do not enter the enclosure; ESL provides a removable cover over the cam openings in the bottom of the enclosure. The cover is removed and stored on the inside of the door when in use by the generator.
How much does it cost to install a StormSwitch™?
Costs will vary depending on amperage, local contractor rates, whether this is part of new construction or an addition to an existing installation, etc. However, rest assured, the ESL StormSwitch™ is designed for easy installation. The StormSwitch™ is designed to mount to a vertical surface with (4) external bolts. Utility input power can be from the top, back or side. Load exit is through the back, bottom or side.
What happens after the utility power is restored?
Once utility power is restored, simply turn “OFF” the generators disconnect. Shut down the generator itself. Open the StormSwitch™ door. Disconnect the generator cams. Replace the cover over the wire openings. Close the StormSwitch™ door. Turn the utility power “ON”
How does the StormSwitch™ compare to a standard "double-throw" or "double-key" transfer box?
The traditional “safety switch” and/or “double-throw” switches do not provide the over current protection option that is available in ESL’s StormSwitch™. These “safety switch” and/or “double-throw” switches are intended for “hard wiring” and therefore would require a licensed electrician (difficult to find one available as they are in high demand during power outages) to connect and disconnect the generator.
What is UL 1008?
This Underwriter Laboratories listing ensures that the consumer receives a dependable, safe product that has undergone environmental, temperature, endurance (6000 operations for the 200 ampere unit)) and short circuit testing. Products Listed under UL Standard 1008 comply with NEC requirements Article 702 for optional standby systems. |
