What does 'mixed lines' mean with regards an EICR?

[HappyHippyDad]

A customer has just rang. His daughter lives in Scotland and has just had an EICR carried out. Part of the report says 'mixed lines'. He really didn't have many more details, he seemed to think it was to do with new cables being put in.

I realise this is very vague, but just wondered if 'mixed lines' was a recognised term for something?

Personally I'm guessing it is just another way of saying mixed colours, but if so it's a bit odd.

They need to get themselves sorted out!

Indeed they do.

I was recently contacted by a prospective customer who was in the process of selling their house and wanted a quotation for remedial work as mentioned in the Home Report:

the electrical system is on mixed lines and this should be checked and upgraded by a registered electrical contractor.

Upon visiting the property to determine what needed to be done, I noticed that the installation was on a looped supply. This is commonplace in the four-in-a-block 'cottage flats' that are to be found across Glasgow. I then contacted the surveyor who produced the Home Report to ask if he had meant 'looped supply' when he wrote 'mixed lines'. He confirmed this to be the case.

I politely advised him to use the correct terminology in future reports so to avoid any confusion. I also pointed-out that supply upgrades are the remit of Scottish Power Networks, not electrical contractors and that he shouldn't be offering such advice.

From an electrical installation perspective, the home reports that I have read are about as much use as window wipers on a submarine.

Yup.

'Mixed Lines' - Possible Polarity issue?

If a Scotsman has written down 'mixed lines' it could mean literally anything.
I had a conversation with a chap from Aberdeen 3 years ago, to this day I haven't a clue what he was on about, I just replied with nods and countless yesses.

And I've a feeling if he had written the conversation down, I still wouldn't of made head nor tail of it!
