DENKO’s low-voltage electrical design workspace
A free set of calculators for choosing breakers, cables, conduit, cable-rack width, and grounding conductors for low-voltage installations.
- For
- Electrical designers working on low-voltage circuits
- Worth noticing
- The example result links a 15 kW, 200 V, three-phase load to a 60 A breaker and 14 mm² CV cable, with a 30 m run.
Field notes
The selection workspace exposes assumptions that can materially affect a result, including ambient temperature, a user-set derating factor, and the target voltage drop. Its example circuit reports a 48.1 A load current and shows candidate equipment through a circuit overview. The page directs users to verify matters such as short-circuit current and protection coordination separately, so it is positioned as an initial design aid rather than a final engineering sign-off.
