32amp commando socket in house?

gazfocus

Not really sure if the best place to ask this but I’m looking to move some of my business equipment home and one of the machines has a blue 32amp commando socket (as pictured). Is there any reason I wouldn’t be able to have a 32amp commando socket wired into my home fuse box? 

I’ve checked the power requirements for the machine and it runs at 25amp with a max consumption of 6Kw. 

I’ve currently got this machine in an industrial unit that has 3 phase power but I don’t believe the machine requires 3 phase.

If it's a blue 3-pin plug, then it's single phase 230V.

There's no reason why you can't have a commando socket fitted if you want.  But a 32A socket will need its own dedicated 32A supply from the consumer unit.  You can't just tap into an existing ring main.

1. If the machine has an induction motor in it, they can present a load of between 3 and 6 times their normal running current at start up.  That could be 75 to 150 amps, and most home incoming power is rated at 80 or 100 amps.  You might need to consider some form of soft start device.  Best to consult a qualified electrician.
2. The plug in your photo is a single phase one, not three phase.

You'll probably want a type C mcb in your consumer unit as well - Needed one when I installed some big toys in the garage.

Thanks for the replies. A dedicated circuit in the consumer unit isn’t an issue, it’s not something I’d be doing myself of course, but just wanted to know if it’s a possibility more than anything so I can start making plans. 

Thanks again

As others have said Blue plug is 240volt (single phase) 3 phase plugs are red, 110 volt yellow. Homes have a 60A supply so no problem. Seperate Type C mcb (as freebear said) if you want to run big toys.

The start up load would not be for very long, and your incoming mains supply will be happy with an overload for a short time.  You can find tables showing how long you can overload a fuse before it blows, and it is a surprisingly long time. That’s reasonable, as the purpose of the fuse is to prevent the cable overheating, and it takes time for the temperature to rise.
