haven't a clue mate that's why I posted on here still haven't tried it yet I no it will run to fill the tank first time but not sure if it will start under load when the pressure in the tank drops
I run a 3 hp Clarke of similar spec and it pops a 13amp plug fuse every time it starts. I ran a separate circuit with a 20amp C type Mcb ( B type tripped occasionally) and have had no trouble .
