What is Electrical Installation and Maintenance NC II?
EIM NC II covers residential and building wiring: roughing-in and cabling, installing protective devices and grounding, and installing outlets, switches and lighting fixtures — following the safety rules of the trade.
It is a common starting point for electricians and is taught in senior high school TVL tracks and TESDA training centers.
What you will learn
The core units of competency in the Electrical Installation and Maintenance NC II Training Regulation are:
- Perform roughing-in activities, wiring and cabling works for single-phase distribution, power, lighting and auxiliary systems
