Hi , I have an asphalt testing machine and would like to add a surge protector to it. I have single phase 240 coming into a 40 amp main breaker on my machine. What size of surge protector should I get and how would I wire it to the machine?

It is very much UK-centric but this guide might help:

Many makes of distribution board now offer SPD options, so you really ought to get a professional to look at what can be fitted to your one as that then protects all of your equipment.

If you don't expect high surge energy (no overhead supply lines, no lighting protection on building, etc) then you get "Type 2" SPD that are reasonably priced, in the $100-200 region for single phase. If you do have a risk of high energy impulses then the "Type 1+2" offer around a magnitude more energy capacity but at around 4 times the cost.

When checking specifications of peak current, remember that the 10/350us waveform used for type 1 testing on a direct hit has much more energy than the same current in the 8/20us waveform used for induced surges when testing type 2 SPD.
