If you are as competent as you like to imply then why do you have to hide your identity?
More competent, more experienced and more qualified than you that I guarantee! I don't hide my identity, I just wouldn't put my details up on an open internet forum, only fools do that.
Would you like to explain, in proper technical words, why a fridge compressor might produce a current to earth?
The RCD trips when the compressors start up, there is a surge in current therefore a surge in leakage current. This is due to how the motor and it's windings are constructed, they introduce a capacitance.
Other equipment like IT equipment and their power supplies also trip RCD's due to high earth leakage current. This is due to this type of equipment having noise filters, basicaly capacitors between L & E, N & E.
When power is applied these capacitors see numerous frequency's added together and a capacitors impedance reduces as the frequency increases creating a larger earth leakage at the point of switch on.
Apprenticeships were generally for people who left school at 16 to "learn a trade". A long time ago they did give good experience when the trainee was going to work in the firm for a long time.
No they are not just for 16 year olds and they are still the only way to train properly in a trade subject, I have an apprentice at the moment and he is exposed to all aspects of the plumbing and heating trade, renewables and will be taught some electricals when in the fourth year.
He when qualified will be a well trained operative who would wipe the floor with any short course chump when in the third year no problem.
I wonder if you saw the Peltier effect device at Installer Live?
No I didn't, I don't have time like you and other one man bands and there tin pot empires, sitting around all day waiting for the phone ring for a cr4ppy boiler repair.
I have a business to run, employees wages to pay and work to quote/estimate for whilst tendering for local authority/government contracts.
Now lesson over! when are you going to admit you were WRONG or are just a total egotistical, inexperienced and under qualified a4rsehole.
