Grounded 3-Wire Power Extension
The grounding conductor is the key structural difference between 2-wire and 3-wire extension cords.
For compatible grounded equipment, a 3-prong extension cord maintains the grounding path through the extension connection when properly matched and used.
Depending on the model, available configurations may include:
- 3-wire grounded construction
- US 3-prong plug
- Grounded receptacle
- Different AWG conductor sizes
- Multiple cord lengths
- Single or multiple outlet configurations
- Different jacket colors
- Molded plug and receptacle assemblies
Designed for Indoor Equipment Requiring Grounding
A 3-wire indoor extension cord can be used with compatible equipment requiring a grounded connection and additional distance from the wall receptacle.
Typical applications may include:
- Computers and office equipment
- Monitors and printers
- Household appliances
- Audio and video equipment
- Indoor workshop equipment
- Commercial electrical equipment
- Other compatible grounded devices
The actual suitability depends on the cord's electrical rating, conductor size, length and the load requirements of the connected equipment.
Selecting AWG Size and Cord Length
For B2B buyers, extension cord selection should not be based on length alone.
Conductor gauge, cord length and intended load are interconnected. A longer cable run can introduce greater voltage drop, while different AWG sizes have different current-carrying characteristics within their applicable product construction and rating.
For OEM projects, these parameters should therefore be specified according to the intended equipment rather than simply selecting the lowest-cost cable configuration.
3-Wire Grounded Construction
The three-conductor design typically includes line, neutral, and grounding conductors, providing a grounded connection for compatible equipment.
Wire gauge, insulation, jacket material, and electrical ratings can be selected according to the intended application. Buyers should provide equipment requirements and target-market specifications for proper configuration.
Quality Control
Production follows approved product specifications, with quality checks covering conductor construction, grounding connection, plug and connector assembly, insulation, electrical performance, cable dimensions, and visual appearance.
Relevant testing and certification documentation can be provided according to the final product configuration and applicable North American market requirements.
