3 Phase Power & Plug Connections — What You Need to Know
If you’ve purchased or are considering purchasing a 3 phase machine, one of the most common questions we get asked is: “Does it come with a plug?” Generally speaking, the answer is no — and here’s why.
How 3 Phase Machinery Is Disconnected
When industrial machinery is decommissioned from a factory or workshop, it is typically disconnected directly from a switchboard by an electrician. This means the machine leaves its previous home without a plug fitted, and in some cases the cable itself may also be absent. This is simply how the process works at an industrial level — it has nothing to do with the age or condition of the machine.
What This Means When You Buy Second Hand
As a machinery dealer, we are not electricians and are unable to supply or fit plugs. What we can tell you is that this situation is no different to buying a brand new 3 phase machine. New machinery purchased through any supplier or manufacturer also arrives requiring a licensed electrician for installation and connection. Second hand or new, 3 phase machinery requires a professional to get it running safely and legally.
If you don’t already have a relationship with an electrician, it’s worth organising one before your machine arrives. Connection is usually straightforward for a qualified tradesperson, and having it sorted in advance means no delays getting your equipment up and running.
When a Plug Is Already Fitted
On occasion, a machine will come into our inventory with a plug already fitted — perhaps from a smaller workshop setting where it was connected that way originally. In those cases, the plug stays with the machine. For the same reason we don’t fit plugs, we don’t remove them either.
The Bottom Line
3 phase connection is a licensed electrical job — full stop. Plan for it, budget for it, and you’ll have no surprises when your machine arrives.
