Dear Sir,

I want to know cable & wire requirements for a

1 BHK
2 BHK
3 BHK
4 BHK

I need by types and quantity required.

Thanks & Regards

Kumar.

Hi Kumar,

The amount of cable and wire requirements for the BHK will depend on a few factors including:
The size of the BHK, the local codes that will apply to the BHK flat, and what electrical appliances and equipment will be installed or used in the BHK.
For example, a central aircon unit for a 4BHK will be much larger that a central aircon unit for a 2BHK, however if each room will have its own aircon then each room will need ample power to supply the aircon plus then regular outlets that will be located in the bedroom.

Plan with the end in mind. Gather as much information about the BHK electrical requirements first, then plan out your electrical cable and wiring requirements.
I hope this helps,
Dave
