Without access to critical types of data, communications can be adversely affected, necessary medical data could be unreachable, emergency plans inaccessible, and emergency service personnel can no longer function. How do we prevent a situation like this from occurring? This question and others just like it have the electrical industry standing at attention and taking notice. One of the solutions is through the incorporation of critical operations data systems.
In general, electrical designers, contractors and regulators are quite comfortable in applying the CE Code requirements for the electrically connected life safety systems. However, they must have a clear understanding of such requirements in other relevant codes and standards.
For some time, the proper control of emergency lighting circuits has been a topic of debate for manufacturers, systems integrators, and specifying electrical engineers. Much of the debate has centered on the proper application of the many codes and standards that apply to emergency lighting.
Let’s say, you are a supplier of an emergency generator or a designer of an emergency distribution system, and your task is to select an emergency generator and main disconnecting means and overcurrent devices that will manually or automatically disconnect the electrical system supplied from the emergency generator.
Let say, a designer decides to install a backup power supply for the IT network in the office, or to provide an alternate source of power to the sump pump in a building. Or a decision is made to have a standby power source for lighting in all classrooms of a high school. Or what [...]
Significant growth in optional standby systems for commercial applications is being driven by the demand for electrical power to be present that will ensure continuity of business activities. Concerns stem from weather related outages to other reliability issues that can result in the loss of electric utility of a building, communication center, or process. Loss [...]
Code users often ask whether Section 46 of the CE Code governs only the requirements for emergency systems that are mandated by the National Building Code of Canada (NBCC) to provide alternate source of power when the normal power fails. Some of the Code users feel that Section 46 also covers wiring to the emergency [...]
NEC-2008 has a new Article 708, Critical Operations Power Systems (COPS). COPS are defined as “power systems for facilities or parts of facilities that require continuous operation for the reasons of public safety, emergency management, national security, or business continuity.” The article also defines designated critical operations areas (DCOA) as “areas within a facility or [...]
The 2005 edition of the National Building Code of Canada (NBCC) has been already adopted by the majority of provincial and territorial jurisdictions. This means that one change that has been introduced into the latest edition of the NBCC could be very interesting (and very relevant) to the electrical designers, installers and electrical safety regulators. [...]
Most likely, by way of our television sets, we have all witnessed the unbelievable destruction and devastating consequences of one or another natural disaster. Certainly, hurricane Katrina and the December 26, 2004, Indian Ocean tsunami come to mind. For sure, many of you may also have been personally involved and will have a never-ending memory [...]
