16A Extension Board Buying Guide — Power Up Safely and Smartly
Choosing the right 16A extension board is not just about getting extra sockets — it’s about ensuring safety and performance for your heavy appliances. Whether it’s a geyser, air conditioner, refrigerator, or microwave, using the right board can prevent overheating and electrical hazards.
In this guide, we’ll help you understand how to select the perfect 16A extension board for your needs.
What Makes 16A Extension Boards Different?
Most homes use 6A sockets for small devices like fans, TVs, and chargers. But for heavy-duty appliances, you need something more powerful.
| Type | Suitable For | Load Capacity | Plug Type |
|---|---|---|---|
| 6A Extension Board | Fans, TVs, Laptops | Up to 1000W | 2-pin/3-pin small plug |
| 16A Extension Board | Geyser, AC, Washing Machine, Microwave | Up to 3000W | Large 3-pin plug |
💡 Tip: Always match your appliance plug type and wattage before purchasing.
How to Calculate Load and Choose the Right Cable
To ensure safety, you must know your total load (in watts).
Here’s a simple way to calculate:
Total Load (Watt) = Appliance Wattage × Number of Appliances
Then, match it with the right cable size:
| Total Load | Recommended Cable Size |
|---|---|
| Under 1000W | 0.75 mm² |
| Under 1500W | 1.0 mm² |
| Under 2000W | 1.5 mm² |
| Under 3000W | 2.5 mm² |
Key Features to Look for in a 16A Extension Board
When buying online, don’t just look at the number of sockets. Check for these essential safety and performance features:
- ISI Certified Cable – Ensures quality and reliability.
- Fire-Resistant Body – Prevents melting and fire risks.
- Heavy-Duty Brass Sockets – Long life and low heat build-up.
- Fuse Protection – Prevents appliance damage during voltage surge.
- Proper Earthing – Protects from electric shock.
💬 Pro Tip: Avoid cheap boards with thin wires — they may look similar but often can’t handle 16A safely.
