Not sure how your phase converter is setup up, but I strongly suggest you make sure it won't start back up on its own in the event of a power failure and return to power. Could be very dangerous. Make sure you ALWAYS have to manually start the phase converter.
I have one in my shop - generates 3-phase (one a little wild) and then I step up the 220 to 380v and send it to my grinders.
I have a circuit - you can look at mine and strip down.
I have circuit breakers and contactors I have a box that holds them - pro grade - and a hand plug that plugs into my 220 plug in the shop. (I have a 30x30 building) From the box I have 22o on a second local breaker - and a contactor that switches 220 to the rotary. Rotary comes back through a breaker to a contactor and then to distribution sockets.
I have extension cords on mine - 3 phase ones - but some want to wire and use more often than I. My grinders are 1% use. Want to get rid of one.
If you want the design - I might be able to find it - and send you a copy.
Mart> Rotary converter will be installed in my garage and used to run lathe& mill

Just for your amusement. Friend reports that one of the main machines is down at work. It had been acting up, errors in Z, and last week - it tripped the breaker. Somehow, he didn't know, and I couldn't follow the explanation on possible causes (out of my area of understanding.) 1400 amp, 3 phase, 430 volt service. tripped the breaker. "Ooops".
Good news - with that machine down, he can get Holy Week off.
Worse news, the supply factory for the inserts for the 2 inch face mill which does the majority of their work - is dun got washed away. So, they have about a week's supply on hand and then .... they do not even have enough on hand to cover wheel they scramble for a replacement.
Since, surprisingly, your house hasn't ( yet ) caught fire...
In the case of my installation, the OUTPUT side is into a 20 circuit 3ph breaker panel and if I were to put a 30 amp fuse there at the output it would barely allow even running the air compressor let alone the rest of the machines that are wired onto the buss...
--FWIW the input side is a 125 amp breaker which feeds single phase to the idler which is a 50 hp Toshiba Hi E
BTW, whoever it was here that mentioned using a contactor and definate start /stop circuit to forbid auto-restart upon power fail or brown-out is spot-on..
--You definately want the magnetics to drop input power altogether in this instance otherwise you will get huge HV transients sent down the line--not good if you have any computers or equipment that uses varisters to protect against spikes.
