Electrical Installation

Location Box Requirements

• The EC Socket should be mounted on the location box.
• The location box should be painted with black and yellow stripes for visibility.

Copper Cable Screen and Armour

• The screen and armour of copper cables should be jointed using suitable wires.
• This ensures proper screening and earthing at stations, meeting specified screening factor.
• This process should be done before any other steps to prevent electric shock from induction.

Copper Cable Earthing

• The copper cable screen and armour should be earthed using a low value earth.

Location Box Requirements

• The EC socket should be fixed to the location box.
• The location box should be painted with black and yellow stripes.

Copper Cable Joint Requirements

• The screen and armour of copper cables should be jointed with suitable wires.
• This ensures the specified screening factor, crucial for earthing at stations.
• This step should be performed first to prevent electric shock due to induction.

Copper Cable Earthing Requirements

• The copper cable screen and armour should be earthed with a low-value earth.

Location Box Safety

• Location boxes should have EC Sockets installed for convenience and safety.
• Location boxes should be painted with black and yellow stripes to increase visibility and act as a warning.

Copper Cable Safety

• Copper cable screens and armour should be jointed with suitable wires to ensure proper earthing at stations.
• This jointing process is essential for achieving the specified screening factor, which minimizes electrical induction and potential shocks.
• Jointing the copper cables before any other electrical work helps prevent electrical shocks due to induction.

Earthing Practices

• The copper cable screen and armour should be grounded with a low-value earth connection to minimize electrical hazards.
