Before & After III

Here are the 3 Phase Plugs for the control cabinets being made.  To begin with, you’ll see the connection points waiting for screws to be loosened and for crimped cable-ends to be inserted and secured.

You’ll notice 3 brown cables, 1 blue cable, and 1 yellow & green cable connected to each plug.

• L1, L2, and L3 marked brown cables are Live.
• N marked blue cables are Neutral.
• Green & Yellow cables are Earth.

A 3-phase plug delivers three-phase alternating current to high-power machinery, industrial equipment, or heavy-duty commercial appliances.

Unlike standard 3-pin single-phase plugs, these connectors feature 4 or 5 pins to manage three separate live (active) phases, ensuring balanced, consistent power, typically at 400V-415V in the UK.

You can also see one of many completed plugs on the Workshop shelf here as an example of an assembled 3 Phase Plug.
