    You would run 3 core + cpc from the roomstat back to the wiring center. Sleeving all cables appropriately. My drawing just shows how it needs to be connected.

    If your motor is 4.5kW using your method you would do the following: 4.5kW in Watts = 4500W 4500W / 3 = 1500W (This is where you divide the power of the motor by 3 for the 3 phases) 1500W / 230V = 6.52A (This gives you the current per phase) 6.52A * 1.1 = 7.15A (This applies the 10% for max...

    Evening, Matthew on the day of your exam, be sure to check the spec for the install. When I did my AM2, the lighting circuits were wired in: 6242Y = 2 core + cpc 6243Y = 3 Core + cpc I'm not sure if the AM2 changes across the UK so it might well be singles. Just a heads up :)

    Hello, the formula I was given for setting a motor overload is as follows: (Motor current / 1.73) + 30% So take the Motor rating; in Your case its 3kW using I = P / V I = 3000W / 400V = 7.5A Now you divide the motor current by 1.73 (Square root of 3) to get the current per phase. 7.5A /...

    Dimmer switch

    To my knowledge, LED's fed from a transformer, to work with a dimmer, requires a special LED driver for the dimming to work correctly. I may be wrong.

    The AM2 has changed a lot from how it used to be, now you just install cables as opposed to fabricating the installation

    AM2

    Best tip I can give you for the AM2: Write everything on the back of your schedule of test results. R1+R2 at each point, Zs at each point, RCD values x1 and x5, FPC / FSC, 3 phase double PSC value, the more the better. Ring Circuits: Use the formulas to calculate expected R1+R2, Ring...

    NVQ2357 and AM2

    Hello, The way I have achieved this is completing a 3-year apprenticeship and completing the AM2 in the final year after all exams have been completed. My advice would be to find a company that is looking for an apprentice and send your CV. Work 4 days a week with the company and go to college...

    Are these light fittings ok for use?

    I found Thorn to be a good brand. 2ft, 4ft, 5ft, 6ft and 8ft Twin Thorn Fluorescent Fittings - https://www.tlc-direct.co.uk/Manufacturers/Thorn/Fluorescent_Batten_Fittings_1/index.html

    Are these light fittings ok for use?

    Hello, with regards to the light fitting with the sticker on it, this may be due to one of the ballasts being faulty and not allowing the light to work correctly. Also from the picture you posted the capacitor seems to be showing signs of thermal damage, so for that reason I would be reluctant...

    Hello Everyone

    Thanks, What I love about being an electrician is every job is different and you always have to adapt to solve problems. I think I would go insane if I did the same thing day in day out.
