I guess what I was thinking was that although the current in each phase would be 13 amps, because they never coincide you wouldn't simply add them up when considering a single phase equivalent, i.e. that the 3-phase power calculation would be 400 x 13 = 5200, not √3 x 400 x 13. The primary advantage of the stage pin connector over the NEMA5-15 connector (commonly known as an Edison connector in the theatre industry) is its increased durability and resistance to damage due to its more robust construction and the ability to compensate for wear with a pin splitter. Having a distinct connector designated for dimmable power also helps prevent confusion of dimmed and non-dimmed circuits which could lead to equipment damage. Even the smallest stage pin connectors are rated for 20A, which translates to 2.4kW at 120V, compared to the 15A and 1.8kW of the NEMA 5-15. In applications where cables are on the floor, the low profile of the connector allows for connections that are only slightly higher than the cables they connect. Throughout Europe, a common use of industrial power connectors is in the entertainment and broadcast industries.

Our 32 amp plugs and power connectors includes numerous products designed for reliable and safe electricity supply, ideal for serving high demand power applications across a variety of industrial or machinery-driven environments.

It is often asked “Can I change the plug on my machine to a different rated plug?”

If the Machine does not require a Neutral it will only have 4 Wires. You can use a 5 Pin plug but the middle pin will be swaying in the breeze and will prevent you plugging it into a regular point in a building without 5 Pin outlets.

In the Netherlands, Perilex is also used to connect fans with wired speed control (Switched L2 and L3 pins), but fans may not use three phase power A 5 pin plug can be fitted to the Satellite 650, but inside the plug, there will be no wire to the centre pin anyway, so no point.

We have three such loads so they are drawing a total of 9KW. There will be no current in the neutral since the instantanious currents in the three phases sum to zero. Odom, W. (2004).

In Europe, the most common range of heavy commercial and industrial connectors are made to IEC60309 (formerly IEC 309) and various standards based on it (including BS4343 and BSEN60309-2). These are often referred to in the UK as CEE industrial, CEEform or simply CEE plugs, or as "Commando connectors" (after the MK Commando brand name for these connectors). Stein, B. (1997).
