Compliance Check of EPD’s Design Guideline for EVCEI & CoP for Electricity (Wiring) Regulations - PASSED

Compliance Check of EPD’s Design Guideline for EVCEI & for Electricity (Wiring) Regulation Section 26S - Options of Charging Facilities for Electrical Vehicle Installation after Completion of EVCEI - PASSED

EPD Design Guideline -

WITHOUT Load Control System or Optimized Design:

Diversity Factor should be EQUAL to or LESS than 1 [INEVITABLY COMPLY]

WITH Load Control System or Optimized Design:

Diversity Factor should be 0.5 or HIGHER

“TRUE Engineering Design” vs “Current Demand = Summation Loading Design” - SAMPLE COMPARISON

Why not adopt a TRUE Engineering Design?
Why not save 2/3 Installation Cost on sub-main distribution?
