introduction
Proper design and installation considerations can promote optimal use of electrical energy. Electrical installation technology provides the required services with minimum electricity consumption
and security level.
Designers consider this a general requirement of the design process to determine the best utilization of electrical energy.
According to Figure 1 of IEC 60364-8-1.2019, the optimization of electricity use is based on energy efficiency management, which is based on electricity price, electricity consumption and real-time
Adjustment.

This document stipulates the technical requirements for marking and documentation, protection against electric shock, structure, mechanical performance, electrical performance, etc. of load shedding equipment.
The purpose of this document is to provide requirements for equipment used in energy efficiency systems. This document covers load shedding equipment (LSE).
LSE safety guidelines follow the regulations in IEC Guide110.
This document applies to load shedding equipment (LSE) for domestic and similar purposes. Load shedding functionality is used in energy management systems to optimize including
The overall use of electrical energy including production and storage. Load shedding can be used for energy efficiency purposes as shown in IEC 60364-8-1.2019.
This document applies to the operation of LSE under normal circumstances.
---The rated frequency is 50Hz, 60Hz or both, the rated voltage does not exceed 440V (phase-to-phase), the rated current does not exceed 125A, the rated
AC circuit with a fixed short-circuit capacity not exceeding 25000A; or
---DC circuit 1).
LSE is intended to control the energy supplied to one or more loads, circuits or grids when.
---Achieve the specified time and current conditions;
---Receive commands or information from external systems.
LSE is intended for.
---A single device with all the necessary means to control the load (for example, power management functions are embedded in such a device); or
---A unit integrated into a more complex device, or a stand-alone device as part of an electrical energy management system (EEMS); or
---LSE assembled from independent equipment (for example, LSE with external current sensor); or
---A combination of the above.
LSE can have a wireless interface.
LSE is part of the fixture.
1) LSE of DC link is under consideration.
Note 1.This document covers load shedding equipment in fixed installations, including portable equipment connected to it.
LSE is suitable for circuits with anti-shock protection and over-current protection specified in GB/T 16895 (all parts).
Note 2.For example, fault protection (indirect contact protection) can be covered in the following situations.
---In the TT system, the upstream RCOB or RCCB specified in GB/T 16916.1 and GB/T 16917.1.
---In TN systems, upstream overcurrent protection devices.
Note 3.LSE devices for DC links are under consideration.
By its nature, LSE does not provide isolation or overcurrent protection.
LSE is usually performed by trained personnel (see GB/T 2900.73-2008 definition 195-04-02) or technical personnel (see GB/T 2900.73-
2008 definition 195-04-01) installed and used by ordinary people (see GB/T 2900.73-2008 definition 195-04-03).
This document contains all necessary requirements to ensure compliance with LSE type tests based on a single device or based on an assembly of independent devices
operating characteristics.
These requirements apply to the standard temperature and ambient conditions given in 5.1.They are suitable for use in environments with a protection level of IP20
LSE with dye level 2.For those with a protection level higher than IP20 according to GB/T 4208, it is suitable for harsh environmental conditions (such as
LSEs in locations with high humidity, high temperature, cold or dust deposition) and hazardous locations (e.g. where explosions are possible) may require special structures.
If other functions are included in the LSE, these functions will be covered by the relevant standards.
This document does not cover communication aspects such as protocols, interoperability, data security and any other related aspects.
