I dont understand the frustrations regarding all of the above, and i am not challenging anyones competence.
Pat testing has got a bad name, but it is a legal requirement, and if it isn't done properly you can and will be prosecuted.
If you don't have the book, how do you know all the frequencies of formal visual inspections, combined inspection and tests or who should carry out user checks in a hotel or school for example?
This table in the book is guidance only, but if you go over the recommended schedule without carrying out the inspection and test at those frequencies, then you are going to have a seriously bad day in court if someone gets hurt
If for example an appliance failed, but by deducting the resistance of the flex it passed, would you know how to do the calculation from the values in the table, have you memorised these tables and values?
Are you aware of all the touch current values in the tables, and test voltages?
Can you recognise deteriorating equipment, and know what the minimum values are?
Being competent in the eyes of City and Guilds is irrelevant. You have to be competent in the eyes of the Electricity at Work Regs, it is that which will be used to prosecute you if something goes bad. Being competent means suitably trained and experienced, not necessarily hold a qualification. The EAWR states that the relevant code of practice is the document to use, so if you are doing the job without all the information to hand, and at the correct intervals then you are on a sticky wicket. ÂŁ35 for a book that will cover your backside doesn't seem to expensive to me, given that a day in court would be substantially more expensive, and a lot more inconvenient especially for your family if you were to be given a stay in one of her majesties all inclusive resorts, and it does happen.
