Guidelines for Low-Voltage Power Distribution Boards v1.0

🔧 Latvian Electrical Material Wholesalers' Association (LEVA) Guidelines for Low-Voltage Power Distribution Boards

The Latvian Electrical  Material Wholesalers Association (LEVA), in cooperation with leading Latvian electrical designers, low-voltage switchgear manufacturers, and electrical engineers, has developed official guidelines (v1.0) to support the specification, design, manufacturing, and commissioning of low-voltage power distribution boards.

• Applicable to boards up to 1000 V AC or 1500 V DC
• Suited for indoor and outdoor installations
• Intended for energy generation, distribution, conversion, and control systems

📐 Structure of the Guidelines

• 12 parameter groups: including short-circuit resistance, installation methods, IP ratings, and more
• Excel-based configuration template with over 130 selectable technical attributes
• Standard distribution board types: main distribution, outdoor cabinets, control and automation units

🛠️ Commissioning Requirements

• Aligned with Latvian regulations, EU directives, and IEC/LVS standards
• Outlines required documentation, test protocols, CE marking, and routine verifications
• Includes a control form template to support acceptance and compliance checks
