Elec Data Library
Reference data for low-voltage design in Thailand — cable types, ampacity, correction factors, conductor resistance, breaker ratings and utility service limits, each traced to its source table.
Cable Types (TIS 11)
PVC cable codes used in Thailand — 60227 IEC 01/10/53, NYY, VAF, VCT — with sizes, ratings and where each may be installed.
Cable Ampacity
Current-carrying capacity of copper PVC and XLPE cables for every EIT installation group, from conduit to cable tray.
Correction Factors
Ambient temperature factors in air and ground, and grouping factors for raceways and buried circuits.
Conductor Resistance
Maximum DC resistance of class 2 copper and aluminium conductors at 20 °C, corrected to any operating temperature.
Breaker Ratings
Standard rated currents for MCBs (IEC 60898-1), typical MCCB / ACB frames (IEC 60947-2) and NEC 240.6 ratings.
MEA / PEA Service Limits
Meter sizes with the maximum service overcurrent device, maximum load and minimum service conductors.
Traceable to the source table
Every table names the standard and table number it comes from, and the same data drives the calculators. Confirm the edition and utility requirements that govern your project before design use.
