I am compiling a list of the the most common defects encountered during a periodic inspection of the fixed wiring.

My plan is to use a code when compiling the report to save on reporting time.

For example. " The existing circuit directory is inadequate and should be updated with comprehensive and up to date information"

This is a very common defect and would be coded A. B would be the next most common defect. I want to use a maximum of 26 Code with free text to cover the unusual defects.

Has anyone any ideas.

Sounds like you're wanting to make things more complicated than they already are Keith!

No I sympathise .
A few years back I did same thing.
Realising there was a "common core" of defects often found.
There were about 7 or 8 very common, 7 or 8 quite common and 3 or 4 common.
in other words about 20 "old chestnuts".
When I looked up the regs that they did not comply with then it was a list of about 40 ish rather than 20.
I might see if I can dig it out and have a ponder at it, of course the reg numbers will have been amended since and it was before RCD mania crept in.

I used it as a quick memory jog for myself when estimating for disabled grants (showers & extractors mainly or bathroom/shower room conversions)

"zeo Ze - could not switch off.
It was not possible to obtain a true value of Ze (external earth loop impedance) as the supply to the building could not be switched off. The value of Ze stated was obtained with all bonding conductors connected.
zes Ze - specification
A true value of Ze (external earth loop impedance) was not measured as the isolation of the supply to the building does not form part of the agreed specification. The value of Ze stated was obtained with all bonding conductors connected.

This is what I can't understand about the EICRs that I see, the above are limitations to be recorded.

Any results under the circumstances described above are Zs, not Ze and as such, I make a comment that the EICR does not reflect the true condition of the installation.

What is this obsession with filling in empty test result boxes?

Your a very funny man BOD!

But it's not very fair lifting replies from another, er, what's the word, er, er, well another message.

Do you mean the message that jcm256 posted at 9:58 PM this evening which prompted my reply? It had been been deleted unknown to me whilst I was composing my reply for some reason...........

Anyway, before I turn into a pumpkin

I have a better idea. Attack the macro editor in your word processor and have pre-arranged defect descriptions in a drop down box. Your idea would make reading the report very difficult, which is never a good idea if you want repeat work. My method saves all the typing and is easier to use really, and much more readable.

Might be of some use, some comments need to be updated to current regulations, regulation numbering added if applicable.
zeo Ze - could not switch off.

It was not possible to obtain a true value of Ze (external earth loop impedance) as the supply to the building could not be switched off. The value of Ze stated was obtained with all bonding conductors connected.

zes Ze - specification

A true value of Ze (external earth loop impedance) was not measured as the isolation of the supply to the building does not form part of the agreed specification. The value of Ze stated was obtained with all bonding conductors connected.

epi Equipotential bonding conductors - identification
The main equipotential bonding conductors should be identified with durable labels at the consumers main earthing terminal and fitted with permanent labels stating "SAFETY ELECTRICAL CONNECTION - DO NOT REMOVE".

epb Equipotential bonding conductor - bond
This item should be bonded to the main earth terminal with a suitably sized and identified conductor fitted with permanent labels stating "SAFETY ELECTRICAL CONNECTION - DO NOT REMOVE".

eps Equipotential bonding conductor - size
The main equipotential bonding conductor to this item is too small. It should be replaced with a suitably sized and identified conductor fitted with permanent labels stating "SAFETY ELECTRICAL CONNECTION - DO NOT REMOVE".

met Main earthing terminal
A main earth terminal should be installed to allow the correct termination of the earthing conductor and the main equipotential bonding conductors.

hics High earth continuity - steel cpc
The high earth continuity value of ? ohms should be reduced to a maximum of 0.5 ohms.

hicc High earth continuity - copper cpc
The high earth continuity value of ?? ohms should be reduced to a maximum value of 1.0 ohm.

hls High earth loop impedance - socket outlet
The earth loop impedance value of this socket outlet is ?.? ohms. This value should be reduced or the protective device changed to ensure that a maximum disconnection time of 0.4 seconds is achieved.

sb Supplementary bonding required
This item should be fitted with a supplementary bonding conductor.

vem Voltage on exposed metalwork
A voltage of ? volts is appearing on the exposed metalwork. The metalwork should be bonded to earth and the fault creating the voltage should be rectified.

hle High earth leakage equipment areas
This area supplies equipment with high earth leakage values. The supplies to this equipment should have high integrity earthing arrangements as prescribed in Chapter x of the wiring regulations

phel Petroleum - high earth leakage
The measured value of earth leakage current in this circuit is ? mA. This exceeds the maximum value of 100 mA as stated in the "Guidance for the Design, Construction, Modification and Maintenance of Petrol Filling Stations" published by the Institute of Petroleum and the Association for Petroleum and Explosives Administration. A detailed risk analysis or conversion to an approved earthing system should be carried out."
i
r5 Insulation resistance - below 0.5 Megohms
The group insulation resistance value to earth of the outgoing circuits is ?.? Megohms. This value should be improved to a minimum of 0.5 Megohms, with a minimum of 2 Megohms on individual circuits.

ir2 Insulation resistance - between 0.5 and 2 Megohms
The group insulation resistance value to earth of the outgoing circuits is ?.? Megohms and it may be possible that a latent defect exists. The circuits should be individually tested to ensure that a minimum of 2 Megohms is achieved.

ir10 Insulation resistance - below 10 Megohms - petroleum
The insulation resistance value of this circuit is ? Megohms. This value should be raised to at least 10 Megohms.

ir10+ Above 10 Megohms but significantly lower value than in the previous years test
The insulation resistance value of this circuit is ?? Megohms. Although this value is acceptable, it is considerably lower than the value of ?? Megohms obtained in the previous years test. The reason for this deterioration should be found and remedial action carried out.

irne Insulation resistance - electronic equipment
Insulation resistance testing was not carried out due to the presence of equipment/circuits containing electronic components.

irno Insulation resistance - could not switch off
Insulation resistance testing was not carried out as the supply could not be switched off.
