the new iet model forms, how do you interpret them

[johno999]

Hi all
I noticed the new iet model forms no longer have live to neutral IR testing column. They do have L-L IR column, but im assuming thats for 3 phase, wondered what you guys think. all input appreciated

When you say "new" where are you looking?

 

[Risteard]

The model forms always contained Live/Live and Live/Earth. This of course applies to single phase as well as polyphase. Live/Live applies to all live conductors. Why wouldn't it?

L-L can mean L-N in Single phase circuits. The neutral is classed as a line conductor too.

A neutral conductor is not a line conductor. Line (phase) and neutral conductors are all live conductors.

reading his post got worried then. I must not be reading the test certs
wright. please could you tell the IEE to stop confusing people that can not read the appendix on EIC, EICR, MIC test forms.

Yeah sorry got mixed up terminology. Live conductor..... thanks for the correction

wow, maybe need to slow it down if im not to get barked at here. i am aware that neutral is classed as a live. Im also aware that if you go to iet.org & look at their model form for an eicr you will see it is not the same as it used to be. It previously had 4 columns L-L which was for 3 phase, a column for L-N A column for L-E & a column for N-E So I am trying to get my head around what they are trying to say with new style forms which has just two columns. apologies if I wasn't in-depth enough for some!

 

[johno999]

incidentally, you will find easycert also follow the new style IET forms, however there is a function within the software to change it back to 4 column if you desire

It previously had 4 columns

When? Neither the 16th nor the 17th Edition contained that.
