Home wiring: selection of electrical wires and cables

In electrical wiring of buildings, we must be very very careful in selecting the size of wires and their brand. Be prepared to spend more. Here thrift or kanjoosee may lead to fires in building. Reliability of brand must also be kept in mind. Just fame of brand should not be deciding factor. Make sure

1 Copper used is 99.92% pure , electrolytic copper
   ( this copper has least resistance, because of purity).  
  
   Electrolytic copper is expansive Rs 20 to Rs 30/kg
   more than impure casted, reused copper.

2  Gauze of copper is right and not under gauge. 
   Thickness of copper wires is not compromised to 
   reduce cost.

3 PVC coating is also of proper thickness and have right
   resistance.

  PVC must not have inferior plasticisers and content of
  cheap calcium in PVC is not more than required.
