Ok Here are my findings for the EM6910.
Note: As every machine is different and the way it is set-up i.e. Temp settings, steam etc the values are to be used as a guide only. In addition as the Fluke Y8101 current clamp and my Fluke 8060B have their own tolerance and specs; surge currents were not able to be measured as I was using the X 10 range and the response times etc are not suitable to capture high frequency peaks.
1: EM6910 Rated at 2400W at 240V = 10A ( Manufacturers specs) ;D
A: At switch on and as expected, a quick flick to Over Load (surge) and then settle to ~2.6A in sync with the relay (clicking noise you can hear)
B: As the heating blocks warm up less surge events and settles to cycles of about ~2.1A dropping to about ~1.8A
Making coffee:
A: Unit is stable, warm and ready to go.
B: Steam on (small surge to OL) and then steady at ~2.2A
C: Still steaming and hit the coffee button - Bigger surge and then settle to ~4.3A
I was able to get readings as high as 4.6 but quickly fell to ~4.3A.
Conclusion: Manufacturer has allowed a safety tolerance and would suspect that a number of surges would exceed 10A, but would be for a very short time. This is Normal :

All power boards come with a warning that the total load is not to exceed 10A. The standard house hold GPO contacts etc are rated at 10A
Thus the EM 6910 should not be powered from a power board, if other devices are also running from teh same power board

Not unlike Car insurance, if the unit is un-roadworthy or has unapproved mod etc; your insurance can be then invalid.
As the power boards are clearly marked and the EM6910 is rated at 10A, if you had addition units plugged in, and a fire was the result. Then some, could easily argue that your house insurance should not cover the event that you have created, as all the information is clearly available. You choose to ignore and are then responsible

NOTE: As I did not do an extensive range of testing covering all possibilities, Steam, Water and Coffee at the same time with settings to MAX. I can only state with conference that my system does not have a continuous draw that would exceed ~5A but does have surges that exceed 10A (for a very short time).
EM0480 Grinder.
Rated at 128 - 150W Thus at 240V 0.625A using the main on/off toggle switch.
A: Sharp Surges and inital stable draw of 0.310A
B: As the grinding continues, settled to 0.235A
C: In pulse mode; front pressure switch. If I pulsed the unit I got more surges and initial values of 0.415A that quickly followed the values measured above.
Note: Would can only assume that again the manufacturer has allowed a tolerance and depending on the age of the unit and the hardness of the beans etc that the current draw could be greater than the worse case 0.415A that I got for my system.
Closing note: The sooner the law stops impacting on the laws of nature and natural selection... The less I have to fear that the movie "Idiocracy" may be the final reality :-/
