Georgia Low Voltage Practice case studies
Georgia Low Voltage Practice · Put your knowledge to work in context.
The Georgia Low Voltage Practice exam-prep profile is built for electricians, technicians, and installers who work with circuits and systems operating at low voltage - data cabling, communications, fire alarm, security, access control, audio/video, and control wiring - and who intend to demonstrate their knowledge of that trade in Georgia. The material spans ten domains: electrical theory and fundamentals; low voltage cabling and wiring methods; National Electrical Code requirements that apply to low voltage systems; structured cabling and communications; fire alarm and life safety; security, access control, and CCTV; audio/video, data, and control systems; grounding, bonding, and surge protection; safety, tools, and jobsite practices; and Georgia licensing law and business practices. The Georgia Low Voltage Practice case studies are 5 cases and about 3,583 words.
