What is an IP Rating? (IP20 vs IP44 Explained)

The Ingress Protection (IP) rating is an international standard (IEC 60529) that tells you how well electrical equipment resists dust and moisture.

• First digit = protection against solids (dust, tools, etc.)
  
• Second digit = protection against liquids (drips, splashes, jets of water)

Rating	Protection Against Solids	Protection Against Liquids	Suitable For
IP20	≥12mm objects (fingers, tools)	No water protection	Indoor use only
IP44	≥1mm objects (wires, screws)	Splash-proof from any direction	Outdoor & damp environments
IP65	Dust-tight	Water jets	Heavy-duty outdoor/industrial

What Does IP20 Mean for Extension Reels?

An IP20 extension reel is designed for safe use indoors where moisture is not a risk.

Common uses:

• Powering appliances in the home
  
• Office setups requiring extended reach
  
• Indoor workshops (dry conditions)
  

Limitations:

• Not splash-proof
  
• Unsafe for gardens, garages, or outdoor worksites
  
• Limited durability in dusty or damp environments
  

What Does IP44 Mean for Cable Reels?

An IP44 extension cable reel is splash-proof and offers better dust protection.

Common uses:

• Gardens and outdoor spaces (safe for splashes and damp grass)
  
• Construction sites and workshops
  
• Events, camping, and caravans
  

Still not waterproof do not submerge or leave in heavy rain.

IP20 vs IP44 Cable Reel Safety

When comparing IP20 vs IP44 extension reel safety, consider the following:

• Shock risk: IP20 is not water-resistant, so using it outdoors risks electrocution.
  
• Overheating: Both need to be fully unwound to prevent heat build-up.
  
• Durability: IP44 reels are built with stronger casings, making them better for tough environments.
  

When to Use IP20 (Indoor Applications)

Use an IP20 extension reel when:

• Powering TVs, computers, and appliances indoors
  
• Setting up office workstations
  
• Indoor DIY with low-dust, dry conditions
  

Not suitable for: Garages, sheds, damp basements.

When to Use IP44 (Outdoor & Construction Applications)

Use an IP44 extension reel when:

• Mowing the lawn or using outdoor power tools
  
• Running lighting or equipment in gardens or campsites
  
• Powering tools on construction sites
  

If regulations apply (BS 7671 outdoor use), always use an RCD protected extension reel UK

Other Safety Considerations

Why Unwind Cable Reels Fully

Partially wound reels can cause overheating and fire hazards. Always unwind completely for safe operation.

Thermal Cutout Protection

Choose reels with thermal cutouts to automatically shut off when overheated.

RCD Requirements (UK Regulations, BS 7671)

For outdoor use, UK regulations recommend RCD (Residual Current Device) protection to cut power instantly in case of faults.

Cable Size (1.5mm² vs 2.5mm²) & Voltage Drop

• 1.5mm² cable = light duty (indoor, lower loads)
  
• 2.5mm² cable = heavy duty (industrial, long runs, high wattage)

Guide: How to Choose the Best 240V Extension Reel (UK)

1. Decide on IP Rating → Indoor = IP20, Outdoor = IP44, Heavy Duty = IP65
   
2. Check cable length → 25m is standard for home & site use
   
3. Check cable thickness → 1.5mm² (light), 2.5mm² (heavy duty)
   
4. Look for RCD protection → Required for outdoor safety
   
5. Choose load capacity → 13A reels handle most domestic tools; industrial models may support higher currents
