Earth Bonding Plug EBP, Schuko, 2 x 4 mm Socket, 1 x 10 mm Stud, 1 Megohm - Desco 231170

An earth bonding point (EBP) plug turns any Schuko socket into the ground point of an ESD workstation. It connects to the protective earth conductor only, with insulating plastic pins in place of live and neutral. The front offers two 4 mm sockets for banana plugs and one 10 mm stud, each tied to earth through its own 1 megohm resistor, so wrist strap, bench mat and floor mat share one potential.

Key benefits

• 1 megohm resistor (1/2 W) per terminal, terminal to earth pin resistance 0.8 to 1.2 megohm.
• Earth conductor contact only, live and neutral replaced by plastic pins.
• Two 4 mm sockets for banana plugs and one 10 mm stud for wrist strap and mat ground cords.
• Permanently sealed housing in yellow impact-resistant ABS, every plug tested after manufacture.
• Works safely whether the socket is switched on or off.

Applications

Common ground point for ESD workstations in countries with Schuko sockets such as Germany, France, Belgium, the Netherlands and Spain. Use for ESD control only, never for earthing electrical appliances. One plug should serve no more than two workstations.

Standards

The 1 megohm resistor limits current to below 0.5 mA at mains voltages up to 240 V AC (reference ANSI/ESD S1.1). The common ground point concept follows IEC 61340-5-1. To test, measure the resistance from each terminal to the earth pin, it must be between 0.8 and 1.2 megohm. Do not open or repair.
