Sanctioned Load Calculator & MCB Load Check
Check your home connected load against the sanctioned load shown on your electricity bill, estimate peak demand in kW and get a planning range for the main MCB.
Your estimated simultaneous peak load (3.51 kW) exceeds your DISCOM sanctioned load (2 kW) by 1.51 kW. If you run multiple ACs, a geyser, and a water pump together, smart electronic meters will record Maximum Demand (MDI) spikes, triggering automatic heavy penalty tariffs or meter tripping. We recommend applying for a sanctioned load upgrade to 4 kW.
Connected Load vs Sanctioned Load
Connected load is the combined rated capacity of electrical appliances and equipment connected to your premises. Sanctioned load is the maximum load your electricity provider has approved for your connection.
The two values do not need to be identical because every appliance normally does not operate at full load at exactly the same time. This calculator estimates likely peak demand from your appliance mix so you can compare it with the sanctioned load on your electricity connection.
How to Calculate Sanctioned Load
- List major appliances and their rated wattage.
- Estimate which appliances may run simultaneously.
- Add their simultaneous wattage.
- Convert watts to kilowatts by dividing by 1,000.
- Add reasonable headroom for future or intermittent loads.
- Compare the result with the sanctioned load shown on your bill.
Your DISCOM determines the officially sanctioned value. This calculator is an estimate and does not alter your approved load.

Calculation Assumptions & Safety
Calculations are planning estimates using the displayed inputs and assumptions, not certified designs or verified provider bills. Actual runtime, generation, cost and wire requirements vary with equipment, installation and operating conditions. Confirm manufacturer specifications and current provider rules. Have a qualified electrician review wiring and backup installations.
Sanctioned load vs connected load
Connected load is the sum of appliance ratings. Sanctioned load is the load approved for the electricity connection by the distribution company. Actual peak demand can be lower than connected load because many appliances are not used at the same time.
Use this result as a planning check before requesting a new connection or load enhancement. Your DISCOM rules, service type, phase requirement and approved protection can differ, so verify the final requirement with the utility.
Where to find your sanctioned load on an electricity bill
Look for a field labelled “Sanctioned Load”, “Contract Demand”, “Connected Load” or the local DISCOM equivalent. These fields are not necessarily interchangeable: use the value specifically designated as approved or sanctioned by your electricity provider. It may be shown in kW or kVA. If it is missing, check the connection agreement or ask your DISCOM; this calculator cannot retrieve your approved limit.
2 kW connection versus appliance load: example
Two 70 W fans, four 9 W LEDs, an 80 W TV and a 1,500 W geyser total 1,756 W, or 1.756 kW, when all run simultaneously. Compare that illustrative appliance load with a hypothetical 2 kW sanctioned limit, then check actual appliance nameplates and your provider's load rules. This is not approval for any specific wiring or breaker.
Common questions
- How do I know my sanctioned electricity load?
- Read the approved-load field on your latest bill or connection agreement. If the label or units are unclear, confirm with your DISCOM rather than deriving an approved value from appliance wattages.
- Is 2 kW sanctioned load enough for a 2 BHK?
- Bedroom count alone cannot answer this. Add the loads that might operate together, including heavy appliances, and review your provider's permissible demand rules.
- Is connected load the same as sanctioned load?
- No. Connected load describes installed equipment ratings, while sanctioned load is the provider-approved connection capacity. Your calculated connected load does not automatically change the approval.
