update all working, however very occasionally on start up yes bollard does trip, so I decided to go with Grump's recommendation unfortunately I have received 2 both 2600W after I ordered 4000W I have been in touch with other sellers asking if their advertised 4000W is correct all have said no either 2200 or 2600. There are some 5000W ones advertised but would these give a nice soft start for the transformer

Or could I use the two 2600W ones I've had delivered in parallel
thanks Chris
