Dual Source Electrical Panels – Simple Guide

🔌 What is it?

A dual source electrical panel connects two power sources (like utility power and a generator). It makes sure your equipment always has electricity, even if one source fails.

• Electrical interlocking: Stops both sources from being ON at the same time.
• Mechanical interlocking: A physical lock that ensures only one source can be used.
• Auto changeover: Switches automatically to the backup source when the main power goes off.

⚙️ Key Details

• Current rating: From 125A up to 5000A (small to very large loads).
• Protection:
  • IP44 → Safe from splashes of water, good for indoors.
  • IP55 → Dust and water jet protection, good for outdoors.
• Indoor & Outdoor use: Designed for both environments.

🏭 Where are they used?

• Factories – to keep machines running.
• Hospitals & Data Centers – for critical power supply.
• Commercial buildings – smooth backup during outages.
• Housing complexes – reliable power for residents.

✅ Why it’s important

• Keeps power running without interruption.
• Protects equipment and people from accidents.
• Works in tough conditions (dust, water, outdoor weather).

👉 In short: Dual source panels with auto changeover are like a smart guard for your electricity. They make sure power is always available, safe, and reliable—whether indoors or outdoors.
