CFE Electrical Meter and Switch Base Wiring Detail drawing

This technical drawing illustrates the complete wiring configuration for a CFE (Comisión Federal de Electricidad) residential electrical meter and switch base installation. The detail shows phase and neutral connections from the service drop (‘De la acometida’) through the meter and into the interior installation (‘A inst. interior’). The circular meter assembly features clearly labeled connections for phase (‘Fase’) and neutral (‘Neutro’) wires, with a dedicated grounding rod (‘Varilla a tierra’) properly connected to the system. The right portion details the switch base configuration with proper wire routing from the base to the receptacle (‘De la base a enchufe’). The drawing follows Mexican electrical code standards with appropriate separation of conductors and grounding provisions. A critical safety aspect incorporated is the clear demarcation between supply-side and load-side wiring, preventing potential backfeed scenarios during maintenance work.
