What is Connected Load?

The connected load refers to the sum total of the continuous ratings of all the electrical equipment and appliances connected to an electrical supply system. In simpler terms, it is the maximum power that your home or facility would consume if every single light, fan, motor, and appliance were switched on simultaneously. This metric is vital for utility companies and electrical engineers to design appropriate infrastructure, such as transformer capacity and wire gauges.

How to Calculate Connected Load (Step-by-Step)

Calculating your connected load is a straightforward process involving three main phases:

1. Inventory: List down every electrical device in your premises. This includes fixed loads like HVAC systems and lighting, as well as plug-in loads like laptops or kitchen appliances.
2. Wattage Rating: Note the power rating (in Watts) for each device. You can usually find this on a label at the back of the device or on its power adapter.
3. Summation: Multiply the wattage of each appliance by the quantity of those items, then sum all results to find the total Connected Load.

Difference Between Connected Load and Demand Load

It is important to note that your actual power consumption (Demand Load) is usually lower than the Connected Load. This is because of the Diversity Factor—the reality that you rarely use your vacuum cleaner, air conditioner, microwave, and hairdryer all at the same time. While Connected Load helps in sizing wires for safety, Demand Load helps in estimating monthly utility bills.

FAQs

Why does my electricity bill show a fixed charge for Connected Load?

Utility companies often charge a fixed fee based on your sanctioned connected load because they must keep that amount of capacity ready for you in their grid infrastructure at all times.

Can I increase my connected load?

Yes, if you add new heavy machinery or air conditioners, you may need to apply for a "Load Extension" with your local provider to ensure your meter and service wires can handle the increased flow without melting or causing fires.
