    Gave up the sparky work years ago ( Big mistake with the wages they are today) but retained a restricted, as needed for my Biomedical work.  Fitter and Turner by trade, but could not run a CNC to save my life today.. Too many changes. Also dropped my MCSE certification, as that got too expensive to maintain.
    OK I had to admit having to look up to see CNC so youre already doing better than me (and quite a few others on CS I imagine). So biomedical, F&T, computer and electrical huh - you make or have something to with prosthetics Im guessing..

    You seem fairly safety-conscious. The mate I was talking about told me how Dunlop Volleys were the stock footwear (rubber soul) and he would sometimes work live hanging off balconies.
    Off topic.. Should be in another post :-) Scientific , Forensic and Pathology actually; Technical consultant, Contract management, Quality and Procurement: with some training tossed in for good measure.

    From a safety aspect, when at home, I often work in bare feet and use ally ladders... Trust me, there are good reasons. Off site, a different approach.

    For further topic matters, I will be taking some current draw readings to asses the surge current of the EM6910 and EM 0480 over the weekend. Do not have access to a full logger but should be able to get some basic rms readings.

      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  :-/
