Switches Switches allow the user to control a load (on/off) Examples Single Double 3 way 4 way Combined Pilot light

Cables Black – hot, connection from the AC source to switch typically Red – return, connection from switch to load White – neutral, connection from load back to the AC source, it closes the circuit Green – ground, protects people from electrically charged metal parts

Size of Cables 14: minimum approved width in United States for residential wiring. In PR we can use it for lamps wiring 12: minimum approved width in Puerto Rico for residential wiring 2: cable used from service panel to distribution panel, passes up to 100A of current

Protection Devices Breakers: work like a fuse, opens current path when threshold is exceeded. This protects the circuits from high currents, no protection to people Ground connection: connection to ground so that users are protected from alternate current paths, like breakers they open the current path but when a current change is found

Service Panel Nude cable comes from transformer It then changes to a white cable and connects to the box From here a connection to breaker and ground is done

Distribution Panels Load balancing: the act of distributing equally all 120V loads
