CEE-7 C 14 Dimensional Verification Gauge for 10/16A 250V Two-Pole Flush-Type Socket-Outlet Mounting Boxes

This CEE-7 C 14 Dimensional Verification Gauge for 10/16A 250V Two-Pole Flush-Type Socket-Outlet Mounting Boxes is a precision dimensional inspection instrument engineered to the exact specifications of the IECEE CEE-7 “Specification for plugs and socket-outlets for domestic and similar purpose” C 14 standard. It is specifically designed for dimensional verification of mounting boxes utilized with 10/16A 250V two-pole flush-type socket-outlets, ensuring mounting boxes conform to precise dimensional tolerances to facilitate proper installation and mechanical compatibility with corresponding socket-outlet assemblies.

Specifications:

• Complies with IECEE CEE-7 “Specification for plugs and socket-outlets for domestic and similar purpose” C 14 standard
• Applicable to mounting boxes for 10/16A 250V two-pole flush-type socket-outlets
• Designed for dimensional verification of target mounting box assemblies
• Manufacturing tolerances for all critical dimensions: ±0.05 mm
• Permits insertion into the mounting box without application of undue force, with the gauge’s flange resting flush on the mounting box surface
• Compatible with fixation using two 3 mm diameter mounting screws
• All dimensional parameters (including radii and linear measurements) specified in metric (mm) units

Test Procedures:

1. Prepare the 10/16A 250V two-pole flush-type socket-outlet mounting box requiring dimensional verification.
2. Position the mounting box on a flat, stable surface to ensure measurement accuracy during testing.
3. Align the gauge with the mounting box opening, ensuring proper positional orientation.
4. Insert the gauge into the mounting box using minimal force throughout the insertion process.
5. Verify that the gauge’s flange rests securely on the mounting box surface, indicating acceptable dimensional fit.
6. Utilize two 3 mm diameter screws to secure the gauge to the mounting box and verify connection stability.
7. Confirm that all dimensional and installation requirements specified in the CEE-7 C 14 standard are satisfied; if insertion requires excessive force or the flange fails to rest properly, dimensional non-compliance is indicated.
