RE Developers are Worried of Transmission Woes
21 Feb 2020
Data recorded over the past years show that short circuits have been the major cause(almost 85%)of fire incidents in industries and households alike.
Problem:
Can you Guess, why? Although some people buy quality equipment, yet they don’t maintain them, leading to deterioration in the quality of wire coverings, It has been noticed that overloading electrical circuits leading overheating of the wires causingdamaged insulation resulting into short circuits,
Solution:
Always use proper sizing of Electrical Equipment as below
Total Load in Circuit (Operational Current in A) |
