GB 50169-2006 "Electrical Installation Engineering - Specification for Construction and Acceptance of Grounding Devices" is a professional technical specification currently in use.
This specification is in accordance with the requirements of the Ministry of Construction's Notice on Printing and Distributing (2122 Annual National Specification Formulation and Revision Plan) for Engineering Construction (Jianbiao [2002] No. 85), and is responsible for the China Electricity Council. Guodian Electric Power Construction Research Institute, in conjunction with relevant units, revised on the basis of the "Code for the Construction and Acceptance of Grounding Devices for Electrical Installation Engineering" GB50169-1992. It has been more than 10 years since the Code was issued and implemented on July 1, 1992.
Many of the provisions stipulated in the specification are quite different from the actual situation, so it is necessary to revise this specification.
It reads as follows:1 General Provisions.
2 Terms and Definitions.
3 Grounding of electrical installations.
General provisions. Selection of grounding device.
Laying of grounding devices.
Connection of the grounding body (wire).
Grounding of lightning rods (wires, belts, nets).
Grounding of portable and mobile electrical equipment.
Grounding of transmission line towers.
Grounding of the secondary system of the dispatching building, communication station and microwave station.
Grounding of the metal sheath at the end of a power cable.
Grounding of electrical installations for power distribution.
Grounding of electrical installations in buildings.
4. Project handover and acceptance.

BG50169-92 corresponds to the construction and acceptance specifications of grounding devices for --- electrical installation projects, rather than the "Code for the Construction and Acceptance of Cable Lines for Electrical Installation Projects", the former article is formulated to ensure the construction quality of grounding device installation projects, promote the improvement of engineering construction technology level, and ensure the safe operation of grounding devices.
Article This specification applies to the construction and acceptance of the grounding device installation project of electrical installations.
Article 1 The installation of the grounding device shall be carried out in accordance with the approved design.
Article 1 The equipment used shall conform to the provisions of the current national technical standards and shall have a certificate of conformity.
Article safety technical measures in construction shall comply with the provisions of this specification and the current relevant safety technical standards.
The installation of the grounding device should be coordinated with the construction of the construction project, and the concealed part must be covered before the intermediate inspection and acceptance record with the relevant units.
The construction and acceptance of the grounding device, in addition to the provisions of this code, should also comply with the provisions of the current national standards and specifications.
I don't know if it's suitable for decoration; The latter article This specification is applicable to the construction and acceptance of power cables and control cable line installation projects of 500kV and below.
The installation of cable lines with special requirements such as mines, ships, metallurgy, and chemical industry should also comply with the relevant provisions of professional regulations.
I didn't find one that was 300mm apart.
