To determine the total power requirement (in kW) for running 6 ACs in a building, you'll need to know the power rating (in kW) of each AC unit. The power rating is usually provided on the AC's nameplate or in the user manual.
Let's assume the power ratings of the 6 AC units are as follows:
AC #1: 1.5 kW AC #2: 1.5 kW AC #3: 1.5 kW AC #4: 1.5 kW AC #5: 1.5 kW AC #6: 1.5 kW
To find the total power requirement, simply add up the power ratings of all the AC units:
Total Power Requirement = Power rating of AC #1 + Power rating of AC #2 + ... + Power rating of AC #6
Total Power Requirement = 1.5 kW + 1.5 kW + 1.5 kW + 1.5 kW + 1.5 kW + 1.5 kW
Total Power Requirement = 9 kW
So, you would need a kW meter that can handle at least 9 kW to monitor the power consumption of all 6 ACs running in the building simultaneously.
