16A 240v/230v single phase plug to 63A 415v/400v three phase socket.
Uses 1m black HO7 2.5mm 3 core cable. Can connect to phase 1, 2 or 3 or all three phases, please advise when ordering.
This adapter cable should only be used by a suitably trained person, it is unsuitable for powering most 3 phase appliances, as it could cause damage and / or trip the power supply.
These single to three phase adapter cables are generally used for testing purposes or to power 3 phase distribution boards from single phase supplies, where there is no 3 phase supply available. You will not be able to use the full capacity of the 3 phase board but it will work.
To convert a 3 phase appliance to run on a single phase supply (like a 3 phase coffee machine or 3 phase motor), you would require a 3 phase converter costing several hundred pounds and will also require a large single phase supply.
Do call if you need any advice.
