I have a 3 phase 30k 60hz generator what would I need to do to use this to power my home ?
You need a Transfer switch, either manual $350.00 or automatic over a $1,000.00 The switch will stop the possibility of back feeding power either from the utility to the generator or from the generator to the utility.
Some 3-phase generators can be reconfigured to deliver single phase power (usually at a lower rating) which would be more suitable for home use. Otherwise you'd have to convert your home to 3-phase power. If you still want occasional grid power, then you'd also need a 3-phase drop from the utility (if that's even an option in your area).
If the voltage is correct and you have access to the neutral the transfer switch is required by NEC. The electrical connections are neutral to the grounded conductor and one line to one leg and another line to the other leg with the 3rd phase isolated. Since the configuration of 3 phase generators may vary it is best to have a qualified professional electrician who has experience with them do the work. Some generators are Y configuration but others are a delta configuration with a tapped neutral. This will result in 1 high leg voltage which will damage electrical equipment. This size generator is best powered by diesel. Hope this helps. I repeat get an electrician who has worked on these units they are seldom a DIY for emergency power for a home most systems are single phase 120/240 volt 60 HZ in North America.
