  • A Question for the Electrical specialists

    I was wondering if anyone who knows a bit about electrical outlets etc would know if using an extension cable off a power point and then putting a double adapter on the end of the extension cable to power both my grinder and coffee machine would be a problem. I dont want to short circuit things.

    I hope my query makes sense to someone...

      Re: A Question for the Electrical specialists

      Double adapters have been A NO NO in QLD for some time.

      Not sure about VIC..  Dont like them any way.

      How long is a piece of string ????


      Mal, can you back me up here :-)

      1: What sort of Extension lead...  

      A: 7.5A / 10A / 15 A  rating

      B: How long a lead ?

      C: Will it be coiled at all ?

      2: What  is the ratings for the  grinder and coffee machine  ( Watts / Current)

      3: What else is plugged into the GPO

      4: What else is on the CCT

      The house wiring has specs... the CCTs have specs and load requirements.. (Were they met and did teh electrician do the right thing ?)

      If you over load it ...  Things can and do go wrong..

      House fires up here already, caus people put a heater on and then add a lot of extra stuff to a power board that is driving another power board that has even another power board plugged in..  

      Dont believe me... Go and have a look at most PCs that are set up...


      In general...  A normal grinder and 1200W - 1300W coffee machine;  should be fine off a double GPO.

      Once you start adding in leads (voltage drops - they get worse with length and the higher powered devices) and other items (power boards etc)  on teh cct you complicate it all.

        Woah just read that other thread. Also thanks for the info AM theres more to it than I though lol.

        I guess because this country is/has become so litigious (sp?) its probably not so good giving some advice on the net. Thanks for the OPINION, rather than direct advice.

        Best thing then is to just ask an electrician...

          Yes and no...

          As I said.. You need to just provide some responses to 1 through to 4 with what you know...

          The leads / power boards and equipment will be marked / identified with the rating... LAW :-)

          Then Mal, myself and others can provide an opinion as what might be suitable...

          Worse case ( you have cct breaker / overload installed) is that you might trip a cct breaker.

          You are  NOT performing electrical work........


          Nor am I providing advice as to how to rewire or mod commercial products etc..

          Thus happy to provide an opinion / advice... All dependant on what you give me

              AM to answer your Qs to the best of my knowledge -

              1 It says 10A, 7m, uncoiled

              2 Expobar 2000 watts (heating element), max 10A, Grinder 100 watts

              3 Not sure what you mean but there are two plug holes next to each other, one has a foxtel wifi thing on it the other hopefully this extension lead.

              4 No clue, it is a relatively new apartment (less than 10years old) A1 build, so would assume everything would be above board.

              Hopefully this is enough info for you

                Hopefully this is enough info for you  

                Ok...

                1: Lead is OK... Minimal but ok as I am assuming you not running it full time, selling coffees to go with viewing of Foxtel  

                2: Total wattage at full load is 2100W...  Now ya cct is rated at 2400W

                Thus you have a little up ya sleave, but remember  the CCT will include other GPOs  So if you have a stack of other stuff ON at the same time...  I would expect that during the heating cycle and or if teh Grinder is used at teh same time... The over load switch could trip..

                PS.  If on the same cct as teh washing machine and or any dryer... IT WILL TRIP AT SOME STAGE.   Also Toasters and other heating type devices are great for tripping over load ccts..

                3:  So you should have a Wall socket with two outlets.  One going to your lead...  This then to a power board- RECOMMEND ONE WITH SEPARATE ROCKER SWITCHES.  More $$$ but much safer and useful.   You only need a 4 port, not sure that you can get a double.  

                This way you can switch teh Grinder off and also you machine when not in use or away for an extended time... You can do it right there... If something goes wrong, or you want to take teh grinder out to clean etc... You dont have to get to teh wall switch, that could be behind something...

                NOTE: DO NOT be tempted to plug other devices into this extension board.  Also check its rating... Nothing less that 10A.

                First thing... Find and check out you Power box and if of a night time... Grab a torch

                A: Plug in teh Grinder and test  

                B: Switch Grinder OFF.

                C: Plug in the Machine and when ya switch on.....



                Make sure you wearing Eye Protection, insulated gloves and teh fire department is on quick dial on ya Phone...






                NO   Only pulling ya leg.






                It will be OK....    

                D: Once it has warmed up and cycling...  Turn on teh grinder and try it..

                [edit]Nothing bad should happen..  They should both remain on...[/edit]

                If it trips.. at any stage -   Then ya CCT is already loaded..

                Turn other things off / un plug and re set ya cct breaker. Test again.

                E: Over time and by looking at the wattage etc  you will be able to work out what is causing your problem.  You will then understand what is on what cct and WHAT units will over load your cct.

                For me.. If the Kettle or  Coffee  Machine or  Toaster  or Sandwedge maker  is on at the same time as the Cloth dryer down stairs.  POP...


                WARNING:   If you trip a cct twice in a row and have NO idea...  Call an electrician ASAP, and unplug the stuff you have played with...  WHILE the power is off......

                It may sound a bit scary and or rough and ready...  But with out tools.. There is a logical way to work it out and to be SAFE.

                    Re: A Question for the Electrical specialists

                    Youve covered it all AM.... ;D 8-)

                    Nothing more to add from my end really except to just back up what you have written. The thing to remember with a lot of the el-cheapo extension cords that you can buy from $2.00 shops these days, is that they are barely good enough to get the 10A load certification, there is NO extra copper in those cables for a safety margin.

                    A 7 Metre cord should be OK (just, as AM has already stated) for the load you are going to apply but please ensure that, nowhere along its length, does the cord become coiled as it WILL heat up. If you believe that you are likely to use your setup in this way for more than a couple of casual occasions, then you should think seriously about getting a sparky to connect in a GPO circuit for you at the site.

                    I dont like extension cords being used in this way either. If its only for a once in a blue moon occasion, then maybe but otherwise, a permanent solution is called for.

                    All the best,
                    Mal.

                      Thanks Mal... A PM has indicated that all is OK and it is only a temp measure.

                      I know we all do it at times and I am a lot like many others...

                      Do as I say, not as I do

                      It like telling people to back up their data... Lost pics and other electronic items are usualy gorne for ever... And afterwards is too late

                      I have a NAS and a number of back up systems and all to often spend many hrs recovering data for people and companies... I always say - BACK UP... But I do not always follow my own advice : :

                      With electricity, however; it can and does kill when you stuff up and or forget... And the insurance companies like to find an OUT when it comes time to pay...

                      When I look at a site, my mind evaluates many things, when it a request for info on a forum.. It is a bit harder as one relies on FACTS that are relayed... And Assumptions can get in the way...

                      Thus, a second set of eyes and a confirmation / re affirmation on points is welcome, for me and the initiator...

                      Thanks...
