Grounding Requirements Clause Samples
The Grounding Requirements clause sets out the obligations for ensuring that electrical systems or equipment are properly connected to the earth to prevent electrical hazards. Typically, this clause specifies the standards or methods to be used for grounding, such as requiring all metal parts of electrical installations to be bonded and grounded according to national or local codes. By mandating these requirements, the clause helps protect people and property from electrical shock, fire, or equipment damage, thereby ensuring safety and regulatory compliance on a project or premises.
Grounding Requirements. Interconnection Customer shall tie the ground for its transmission line to the Interconnection Customer’s facility to the ground grid of the Transmission Owner’s facilities at a point provided by the Transmission Owner.
Grounding Requirements. The maximum desired ground grid resistance for the project’s 13.2kV substation ground grid is 23 ohms for an 8,000V ground potential rise. Or, the ground grid resistance shall be no greater than that which would exceed the step and touch voltage limits of E step = 3134 volts and E touch = 885 volts according to IEEE Std. 80 for a supply system clearing time of 30 cycles as a minimum. The Generator-Owner is responsible to limit the ground potential rise (GPR) for communication conductors entering their substation that must be safeguarded and mitigate the zone of influence (ZOI) for point where the GPR is 300 volts peak asymmetrical of the voltage variations on the surface of the earth considering all systems connected having earth return paths. The Generator-Owner should consider the effects of lightning when designing surge protection for the telecommunications equipment. Refer to IEEE Std. 80 for design of a substation ground grid. The Generator-Owner shall provide the results of the ground grid design calculations and the test results for the ground grid resistance Effective Date: 6/23/2013 - Docket #: ER13-1320-000 - Page 43 NYISO Agreements --> Service Agreements --> SGIA No. 1988 between Niagara Mohwak and WM Renewable Energy according to ESB’s 752 and 753. The Company recommends the 4-point Fall-of-Potential Method of testing; refer to IEEE Std. 81 for testing method standards.

Grounding Requirements. For the safety of operating personnel, the instrument must be grounded. The central pin on the AC plug grounds the instrument when properly connected to the ground wire and plugged into proper receptacle. TO AVOID PERSONAL INJURY DUE TO SHOCK, THE THIRD WIRE EARTH GROUND MUST BE CONTINUOUS TO THE POWER OUTLET. BEFORE CONNECTION TO THE POWER OUTLET, EXAMINE ALL CABLES AND CONNECTIONS BETWEEN THE UNIT AND THE FACILITY POWER FOR A CONTINUOUS EARTH GROUND PATH. THE POWER CABLE MUST MEET IEC SAFETY STANDARDS.
Grounding Requirements. Interconnection Customer shall design, install, and maintain grounding facilities to ground the Interconnection Customer’s Interconnection Facilities, in accordance Applicable Reliability Standards and Good Utility Practice. Interconnection Customer shall be responsible for detailed modeling and evaluation of the interconnected grounding system at the location of the Transmission Owner’s Interconnection Facilities and Interconnection Customer’s Interconnection Facilities. If Transmission Owner so chooses, Transmission Owner shall have the right to approve the grounding system design to insure that the grounding system properly protects the Transmission Owner’s Interconnection Facilities.
Grounding Requirements. Grounding guarantees the safe and stable operation of power supply and the CDMA2000 system equipment requiring special attention. In general, grounding includes the working ground, protection ground, and building lightning-proof ground. Normally, the working ground, protection ground, and building lightning-proof ground of the equipment room shall be separately prepared. But, due to limitations of the equipment room, combined grounding is also allowed. If separate grounding is used in the NSS equipment room the grounding resistance should be less than 1W. If combined grounding is used in the NSS and BSS equipment room the grounding resistance should be less than 1W.
2.7.1 Grounding system of the CDMA2000 equipment
2.7.2 Grounding requirements of the AC power distribution system
1. The AC power distribution system requires an independent AC safety ground, and the protection ground assures that the AC power will be cut off.
2. Use of the power supply lightning-proof device can prevent interfering signals from entering into and through the AC power network, to guarantee normal operation of the AC power distribution system.
3. The AC power supply provided to computers only requires the live and neutral wires and no protection ground lines.
4. For switches with unstable power networks, or without AC regulators, over-voltage or under-voltage of the power network will lead to the damage of terminal equipment. So inverting terminal equipment for the power supply is recommended.
5. Grounding solutions Connection cables from the grounding rod to the equipment grounding bolts shall have copper cores and shall be as short as possible. All grounding connection pieces shall have anti-corrosion protection. Grounding bolts must be fastened mechanically. A minimum distance of 50 foot is required between any two different grounds.
Grounding Requirements. Interconnection Customer shall tie the ground grid for its transmission line from the Interconnection Customer’s Generator Facilities to the Point of Interconnection to the ground grid of the Transmission Owner’s Stand Alone Network Upgrades at a point provided by the Transmission Owner at the Point of Interconnection.
Grounding Requirements. All meter equipment shall be bonded and grounded in accordance with the National Electrical Code (NEC) and the Washington Administrative Code (WAC).
