Where a successful installation begins and ends: Understanding NEC rules about wire temperature ratings, terminations
IAEI Magazine Share    
Most electrical inspectors are aware that confusion about wire temperature ratings and equipment termination temperature requirements will likely result in a rejected installation. Information about this topic can be found in the National Electrical Code
(NEC), testing agency directories, product testing standards and manufacturers' literature, but many electrical system installers and designers typically do not consult these resources until after their installation has been rejected. an inspector who is willing to teach can help ensure that future installations are correctly approached by the installer or designer.

Half of Ontarians hire unlicensed
electricians
CBC Share
Almost half of all homeowners in Ontario permit
unlicensed contractors to do electrical wiring in their homes, a survey suggests. On Jan. 1, 2007, provincial legislation came into effect requiring all electrical work to be performed by licensed electrical contractors. Lucy Impera, registrar for licensing and certification of the Electrical Safety Authority, which oversees licensing laws in the province, says awareness of the new legislation - and the dangers of not abiding by it - is low.

Breakers key to process integrity
Industrial Maintenance & Plant Operations Share
Crucial to maintaining process integrity is the circuit breaker. Installed throughout a plant's electrical distribution system, they help protect equipment, personnel and, ultimately,
processes from the damage of ground faults, overloads and short circuits, which can lead to downtime. When properly applied, circuit breakers are coordinated to isolate issues down to the smallest portion of the process, minimizing the effects of circuit interruptions, equipment damage or personnel injury. Proper selectivity coordination is usually the result of a coordination study that examines a plant's electrical loads and distribution system, and concludes with proper breaker ratings and
trip set points.
