Mentor or discussion forum on IET 5th EDITION code of practice

WHERE do I get LEARNING discussion topics and feedback as I would in a classroom format or from a college mentor on many QUESTIONS I have regarding 5th EDITION IET Code of Practice?? 

For example on Page 80 Table 10.6..  1.5 mm cable has a maximum current carrying capacity of 13 Amps.... YET online I am finding PAT engineers testing Industrial extension leads 1.5 mm having 16 Amps run through them and in BLACK cable with BLACK sodding 60309 connectors... EXTREMELY baffelling and not with an axe to grind and as a none electrician am taking the exam soon THINGS are NOT matching up to spec...I need clarification.. I need answers to many seemingly oddball stuff..

Another quick on:   Page 98-99  5th Edition IET..  If you want peeps to get confused this is it:  ES1 is equivalent to Class III ok... then ELV and SELV (no PELV and no FELV??) are WHAT.. class II? 

An exam Q will TRY an TRIP me up over Low Voltage and Extra Low Volts ok.. seemingly obvious YET online sources declare 0-1000 volts AC and 0-1500 volts DC as Low Volts yet another no no no its 120-1500 DC and 50-1000 AC

IF i take that second reference at FACE value on page 99 in the IET we see a table declaring ES2 at 120 volts DC 50 AC  what is that doiing sat right in the MIDDLE of that table??  and what is ES2?  its not clear and I am in mind

to class ES2 as CLASS II...... furthermore in SELV we see a sodding CP being available as basic protection in some cases?????????  Getting really strapped over this guys..

  • I have had discussions with PAT involved persons over the years --Beware - many do not know the regs or count on a client not knowing the regs to charge for unneeded tests. IE--- PAT is Portable Appliance.

    A lot of people these days try to avoid the terms PAT or portable appliance these days - even the IET's code of practice is entitled "In-service Inspection and Testing of Electrical Equipment". From an H&S point of view the duty holder needs to make sure that their entire system is safe, and as wiring regs inspections don't cover appliances (whether fixed or portable), it's often useful have an approach that covers 'everything else'.
