A wiring error detection circuit for providing the status of the wiring of an AC outlet and the status of the AC outlet's ground connection.

Wiring error detection circuit

A network interface device for Ethernet networks using unshielded twisted pair cables comprising an overvoltage protection module and an interconnection module connected to the overvoltage protection module, both modules being connected in series in the Ethernet network.

Network interface device for high speed data lines

A grounding module comprising a housing, an AC plug, a female outlet, a ground sensing-circuit for determining whether or not a ground is present when the AC plug is inserted into an AC outlet and an external ground connection for providing the ground to an electrical device.

Grounding module with an AC outlet

A system for protecting networks from overvoltage and overcurrent conditions.

Overvoltage and overcurrent protection system

Power line surge protection device comprising AC power line overvoltage protection, telephone voice line overvoltage and overcurrent protection, high speed data line overvoltage and overcurrent protection, coaxial transmission line overvoltage protection, and a ground-sensing indicator, all tied to a common ground.

Power line surge protection device

An improved surge suppressor which combines a ground fault circuit interrupter with overvoltage protection for AC power lines. The surge suppressor includes a switchable device for disconnecting power from the ground fault circuit interrupter in the event the AC neutral is lost.

Surge suppressor

A surge suppressor which provides overvoltage protection for AC power lines, coaxial transmission lines and communication lines using a virtual ground rather than a separate ground conductor.

Surge suppressor with virtual ground

Surge suppressor apparatus comprising AC power line overvoltage protection, telephone voice line overvoltage and overcurrent protection, high speed data line overvoltage and overcurrent protection and coaxial transmission line overvoltage protection, all tied to a common ground.

Combination ground fault circuit interrupter/surge suppressor which provides overvoltage protection for AC power lines, coaxial transmission lines and communication lines without a separate ground conductor.

Combination ground fault circuit interrupter/surge suppressor

Residential protection service center apparatus comprising AC power line overvoltage protection, telephone voice line overvoltage and overcurrent protection, high speed data line overvoltage and overcurrent protection and coaxial transmission line overvoltage protection, all tied to a common ground.

Residential protection service center

Residential protection service center apparatus comprising an AC power meter, AC power line surge suppression, telephone line overvoltage protection and coaxial transmission line overvoltage protection, all tied to a common ground.

A customer bridge module for connecting telephone company wiring and subscriber telephone wiring in a telephone network interface apparatus, the customer bridge module having a plug-actuated switchable socket and an overcurrent protection circuit, a half-ringer, a maintenance termination unit or a radio frequency interference (RFI) filter.
