LOAD
Electrical Load Calculator for Home (kW and Amps)
Add up appliance wattage to find connected load in kW, estimated demand and current. A planning aid for electricians and home owners.
Assumptions used EDIT ▾
Connected load is the sum of every appliance's rated watts. Not everything runs at once, so the estimated demand applies a simultaneous-use percentage, which is a judgement: raise it for shops or homes with heavy loads. Current = watts ÷ voltage, assuming a power factor of 1 on a single-phase supply. This is an estimate for planning; sanctioned load, cable sizes and protection must be decided by a licensed electrician under your DISCOM's rules and IS 732.
CONNECTED LOAD
4.35kW
- Estimated demand60% of connected load
- 2.61 kW
- Estimated currentat 230 V, single phase
- 11.3 A
How it’s calculated
Connected load = Σ(watts × quantity); current = watts ÷ voltage
Example: 4,350 W connected × 60% = 2.61 kW demand ≈ 11.3 A at 230 V.
Questions
Is this my sanctioned load?+
No. Sanctioned load is decided by your electricity distribution company. Use this as a planning estimate with a licensed electrician.
