This work presents the analysis of electrical safety for buildings based on IET wiring regulations to decide the conductor size of cable based on ampere carrying capacity under 220-240 V electrical supply. First literature review is carried out with the introduction of significance of power-flow study and reconfiguration to understand the voltage-limits from the source to the load point. Then important few 17th wiring regulations discussed during the design of current capacity calculations of conductors for the fixed and varying environmental temperature. Further, the earthing techniques of are analyzed to avoid from electric shock. According to IET regulations, design current (Ib), nominal current (In), perspective current (Iz), short circuit current (Ise) and percentage voltage drop are calculated for the 2-core, "clipped direct" grouped cabling system. The results and discussions are found useful to set the "time of operation" of IVICB fuse, which help to protect from electric shock. The, sizes of clipped detect conductors are mapped with opted desert temperature conditions such as 34 degrees C, 44 C and 54 degrees C around the cable using standard wiring regulations. According to the temperate variation, it is found that the significant variation in the conductor size of cables and grouping of cable on wall and wall with thermal insulation of used to connect from source to load. Furthermore, in the second part of this case study, the impact of temperature change in Signal Strength, Data Collection and Localization parameters of a Wireless Sensor Network under same desert temperature conditions arc reported.
