I am bringing a piece of equipment into Nth America that will operate from a 3 phase generator. Currently it operates on an Australian electrical supply of 3 x phase 440V + earth (no neutral). Approximate load is 3/50A.

I ask assistance in:
1/ What is USA standard voltage for 3 phase ? (380/400/440/480)
2/ What is Manufacturer & part # of suitable 3 phase plug to match USA 3 phase outlet that would be on a hired Genset (3 phase active + E, No Neutral)?
3/ Where can I purchase Type B wall outlets & mounting accessories (these will be flush mounted on walls but would prefer to include fully enclosed PVC wall boxes) ?
4/ Where can I purchase Type B "appliance inlet/socket inlet" that would enable me to plug extension lead into single phase outlet on genset to make 110/120V 60hz available to power general onboard equipment ?

Any assistance would be greatly appreciated...Thanks.

Who Certifying Body on Minesites ??

Wildleg & Hardworking stiff.......Thanks for reply.

3 phase 480V is suitable for my application (2 x 15KW VSDs & 1 x 3KW VSD)
The equipment will be utilised in the Mining Industry. I expect the onsite Electrician/Engineer will be the Certifier.
Hence any information prior to completion of construction pertaining to US standards would be useful.
Unsure of 1st location but the plant will be travelling between states.

Is an approved Listing Label req'd when piece of equipment is utilised in the Mining industry (purpose built for a particular task) ?

Wendon..thanks also.

The type B socket outlet is for indoor duty.
The type B appliance inlet will be mounted externally.
The 3 Phase 48V plug would definately be outside & sublect to the elements (plugged into genset)

Thanks again Gents !!
