For the Facilitator:
Welcome to the TLE-Electrical Installation and Maintenance 10 on National
Electrical Code
This Self-Learning Module was collaboratively designed, developed and
reviewed by educators from the Schools Division Office of Pasig City headed by its
Officer-in-Charge Schools Division Superintendent, Ma. Evalou Concepcion A.
Agustin, in partnership with the City Government of Pasig through its mayor,
