This is now not a plain DIY router but will be at work so I'm going to try and be as safety concious as possible. I'll come up with the number of relays ill need and then see which way to go.

I got the 625VA transformer, will it be beneficial to build a soft start? From reading and talking to Wobblycogs it's right on the edge of needing one. I well oversized it as I left the 6A in the equation by mistake for the Nema 34 motor that's being powered by a 240V drive!!
