Written by Mark and Claude. A labour of love, many cups of tea, one very long offshore rotation, and a concerning number of late-night conversations with an AI about cable gland order codes.

🔩 Glands: Gland selections are indicative. Always confirm with Hawke datasheets. NPT adapters in hazardous areas require certified adapters and may require an MOC.

Wonder Tool BETA
Enter a motor and supply details — get the correct cable and gland in one step. Based on IEC 60092-352 / NEK 606 / Hawke International.
6.1 Project Details — all fields saved automatically
6.2 Motor & Supply
Running a 50 Hz motor at 60 Hz — with supply voltage raised proportionally — typically increases shaft power capability by ~20% while FLA stays close to the 50 Hz nameplate value. If voltage is not raised, set this to 1.0. Default 1.2×.
Ct = √((90−T) / 45) — base 45°C, 90°C conductor max
⚑ Always use the FLA from the motor rating plate where possible — calculated values are based on typical efficiency class data and may differ from nameplate.
6.3 Cable Selection
Cable ratings are taken from IEC 60092-352 Table B.4.
"These ratings may be considered applicable, without correction factors, for cables bunched together on cable trays, in cable conduits, pipes or trunking, unless more than six cables, which may be expected to operate simultaneously at their full rated capacity, are laid close together in a cable bunch in such a way that there is an absence of free air circulation around them. In this case a correction factor of 0.85 should be applied." — IEC 60092-352 Table B.4

NPT Reference

8.2 Thread Identifier (from caliper OD)
8.3 Adapter Cross-Reference
8.4 Why ¾" NPT ≠ ¾" Anything Measurable
NPT size designations refer to the nominal bore of the pipe the thread was designed for — not any directly measurable thread dimension.
¾" NPT has a thread OD of approximately 26.4 mm — not ¾" (19.05 mm).
For cable entry sizing, always use the catalogue bore figure (e.g. 19.00 mm on the Eaton Redapt ¾"→M25 adapter) — never derive a clearance from the NPT nominal size.
ATEX Note: NPT entries in hazardous areas require certified adapters with full ATEX/IECEx/UKEX documentation. Uncertified adapters require a formal MOC process per IEC 60079-14.
