Study Notes
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.
