This document summarizes an electrical installation plan for a house. It includes an introduction to electrical wiring and circuits. Sections cover electrical symbols, the panel board, notes on switch and receptacle placement heights, and a conclusion that discusses selecting the proper wiring size and protection devices based on the power needs of the house.

3. Introduction
❑Electrical wiring is an electrical installation of cabling and associated
devices such as switches, distribution boards, sockets, and light.
❑Electrical installation circuits depart from its own panelboard
allowing the circulation of electricity up to each utilization point.
❑Each circuit is protected by a circuit breaker mounted in the
panelboard.
❑These circuits consist of electrical wires or cables. Some of them
are connected directly between the protective device and the end
point (case of a receptacle, outlet for hot plates,…). Some others
are connected to the end point through a command device (switch
for lighting, pushbutton for bell,…). And others are connected by
the means of contactors or relays (case of an electric water heater
for example).

8. Notes
❑Switches are normally placed in a room at its entrance, next to the
door, at a height of 110cm AFF (above finished floor). In the
particular case of a multiple way switch controlling a bedroom
lighting from next to the bed, the switch is mounted there at a height
of 55cm AFF.
❑The term multiple gang might be used for switches to refer to
many independent switches of the same type mounted in the same
box or on the same plate.
❑Receptacles should be provided for general purpose use, intended
for the connection of mobile devices, such as vacuum cleaner,
telephone or laptop charger, etc.
❑A receptacle dedicated for a floor or table lamp might be
controlled via a wall mounted switch (called switched power
socket).
Mounting heights of receptacles:
◦ Regular: 30cm AFF.
◦ In the kitchen, above counter top: 110cm AFF.
◦ In garages: 45 to 110cm AFF.
◦ Outdoor: 45cm.

9. Conclusion
After studying the basic power needed for this house, we can now select
the best sizing, wiring and the type of wires, main circuit breaker and
RCD’S.
