Thailand Cable Sizer: a calculator with citations
A forthcoming calculator for sizing cables, breakers, grounding conductors, conduits, and motor circuits under Thailand’s 2021 electrical installation standard.
- For
- Thai electricians and electrical engineers
- Worth noticing
- It lists IMC, EMT, RSC, PVC, and HDPE conduit options, and says engineers must independently verify results.
Field notes
The described input set includes load, voltage, cable length, cable type, and installation method; outputs are meant to cover cable size, breaker, grounding conductor, and conduit or tray. The page says results will cite standard clauses and tables, check earth-fault loop impedance (Zs), and increase grounding-conductor size if a check fails. It also lists offline calculation and cross-device project sync, while saying access is coming soon.
