Preface
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 4026-2010 "Basic and Safety Rules for Human-Machine Interface Marking and Marking of Equipment Terminals and Conductor Terminals"
Identification” and GB/T 7947-2010 “Basic and Safety Rules for Human-Machine Interface Logo Identification, Conductor Color or Alphanumeric Identification”, and
Compared with GB/T 4026-2010 and GB/T 7947-2010, the main technical changes are as follows.
--- Merged Chapter 1 of GB/T 4026-2010 and Chapter 1 of GB/T 7947-2010, adding the scope of inapplicability (see
Chapter 1);
---Added "electrical equipment", "functional grounding", "functional equipotential bonding", "protective grounding", "protective grounding conductor", and "protective equipotential bonding"
The terms and definitions of "connection", "grounding", "equivalence bonding" and "equivalence potential" have been revised to the terms and definitions of "protective conductor" (see Chapter 3);
--- Merged Chapter 4 of GB/T 4026-2010 and Chapter 4 of GB/T 7947-2010, and added footnotes (see Chapter 4);
---Added different marking methods for terminals or conductors when they meet the requirements of protective grounding and functional grounding (see Chapter 5);
--- Chapter 5 of GB/T 7947-2010 is merged, and requirements for line conductors and functional grounding conductors for DC systems are added, 6.2.2
Amend the "light blue" in "blue" (see Chapter 6);
--- Merging Chapter 6 of GB/T 4026-2010 and Chapter 6 of GB/T 7947-2010, adding "intermediate conductor" and "line
Conductor" identification (see Chapter 7).
The translation method used in this standard is equivalent to the adoption of IEC 60445.2017 "Basic and Safety Rules for Human-Machine Interface Marking, Equipment Terminals,
Identification of conductor terminals and conductors.

Basic and safety rules for human-machine interface signs
Equipment terminal, conductor terminal and conductor identification
1 Scope
This standard is applicable to combinations such as resistors, fuses, relays, contactors, transformers, rotating electrical machines and similar electrical equipment (such as complete sets).
Equipment) terminal identification and marking are also applicable to the identification of certain specific conductor terminals. This standard specifies the use of specific colors or alphanumeric
General rules for identifying conductors to avoid confusion and ensure safety. These conductor colors or alphanumerics are used for cables or cores, bus bars, electrical equipment
Equipment and devices.
Basic safety publications are mainly used by technical committees to develop in accordance with the principles of IEC Guide 104 and ISO /IEC Guide 51
Cited when publications.
This standard does not apply to manufacturers or certification bodies. One of the responsibilities of the technical committee is to cite the base when developing standards where applicable.
Basic safety publications, except for specific citations or inclusion in related publications.
