Full title and description

IEC 62852:2014+A1:2020 — Connectors for DC-application in photovoltaic systems — Safety requirements and tests. Consolidated edition (first edition 2014 with Amendment 1 published 2020) defining safety requirements, performance criteria and type/verification tests for DC connectors used in photovoltaic (PV) systems.

Abstract

This standard specifies safety requirements and test procedures for connectors intended for DC circuits in photovoltaic systems (Class II per IEC 61140). It addresses rated voltages up to 1 500 V DC and rated currents up to 125 A per contact, and covers connectors without breaking capacity that may be engaged or disengaged under voltage. The consolidated 2020 publication integrates the 2014 base document and the 2020 amendment(s).

Scope

IEC 62852 applies to connectors used in the direct-current circuits of photovoltaic systems intended to provide Class II protection against electric shock (IEC 61140). It covers connectors rated up to 1 500 V DC and up to 125 A per contact, and is intended for connectors without breaking capacity (i.e., they may be connected/disconnected under voltage). It also covers connectors that can be built into or integrated within PV equipment enclosures and may be used as guidance for some other connector classes.

Key topics and requirements

• Electrical ratings and marking: rated voltage and current, polarity, and manufacturer identification.
• Insulation, creepage and clearance requirements for safe operation at up to 1 500 V DC.
• Mechanical performance: mating/unmating endurance, retention and mechanical strength tests.
• Environmental and durability tests: temperature cycling, humidity, salt mist (where applicable), UV/solar exposure, and thermal stability.
• Contact performance: contact resistance, dielectric strength, insulation resistance and tests for overheating and hot-spot behavior.
• Safety and construction: requirements to reduce risk of electric shock, correct polarity/locking, and suitability for intended PV-system installation.

Typical use and users

Manufacturers of PV connectors and cables, PV module and system designers, testing and certification laboratories, conformity assessment bodies, installation contractors working on rooftop and utility-scale PV systems, and standards/quality engineers specifying reliable DC interconnections for photovoltaic installations.

FAQ

Q: What is this standard?

A: IEC 62852:2014+A1:2020 is the international standard that sets safety requirements and test procedures for connectors used in the direct-current circuits of photovoltaic systems. It is the consolidated edition combining the 2014 base publication and the 2020 amendment.

Q: What does it cover?

A: It covers construction, marking, electrical ratings, insulation and creepage requirements, mechanical endurance, environmental durability tests (temperature, humidity, UV, etc.), contact performance and other tests to verify safety and reliable operation of PV DC connectors up to 1 500 V DC and up to 125 A per contact.

Q: Who typically uses it?

A: Connector and PV-module manufacturers, system designers, testing and certification laboratories, installers and electrical engineers who specify or verify DC interconnections for photovoltaic installations.

Q: Is it current or superseded?

A: The consolidated edition (IEC 62852:2014+A1:2020) is the current published text incorporating the 2020 amendment; IEC indicates the consolidated publication (edition 1.1) with a stability date and remains the active/reference document. Users should check for any newer amendments or revisions after 2020 when needed.

Q: Is it part of a series?

A: IEC 62852 is part of the IEC TC 82 portfolio of standards for solar photovoltaic energy systems and is commonly referenced alongside other IEC standards and regional adoptions (for example EN 62852). It interacts with other IEC documents addressing insulation coordination, PV array design and test methods.

Q: What are the key keywords?

A: DC connector, PV connector, photovoltaic systems, safety tests, LVDC, insulation, contact resistance.
