Thatched wiring - ways to make safer

[pc1966]

A couple of other options?

The sleeving has all of the other issues of basically having to disconnect and reconnect cables, so not far off effort to rewire.

However, the tape might be an idea, no idea how much it would cost to cover all of the cables though - works out at around £1/m but not sure tape length in practice to cable covered, etc.

The sleeving I was originally looking for was the 'self closing' type, but I drew a blank.

But I've just found the product below, which overcomes the dis/re-connect problem. I suspect it may not be quite as effective as I don't think it has a dissuasive chemical component.

Blurb states "optimal protection from rodents and martens". Has to be pretty tough as the latter can eat through almost anything.

Ermmm….. surely all this talk of wraps and covers is irrelevant when the IR readings are saying it all needs replacing anyway??

OP expressed concerns about rodents. Quite likely they wouldn't want new cables chewed, if it turns out the cables need to be replaced. For now we know there has been a poor IR reading, but we don't know for certain that cables are the issue.

Why did I read “Martians” there?

As if rodents weren’t enough….

I had to look up what a marten is, something new every day!

I doubt it stops the chewing as such, probably more makes it taste horrible to them.

Personally I would go for flexi conduit with metal boxes in thatch.
You could replace sections of wiring over time, metal junction box over light position on noggins. There maybe parts of the wiring with internal damage. SWA could work except for urine damage once stripped.
Inspect the wiring every year or so or/and have an electrician test upstairs light circuit only periodically to cut costs.
I passed a thatched EICR recently t/e everywhere, no damage in the last 20 years, another non-thatched had severe rodent damage in a small area 8x heavy duty jcn boxes later bits of cable, after squirrel access blocked. If it were regular occurrence I would go down the flexi steel route. BTW cables were stripped completely in places, no tripping, no dead rodents... a builder noticed it after working up there.... as someone else said 2 MΩ is still a pass but a visual is just as important.

Thanks @sparksfly
I had a brief look yesterday (before realising a dust mask might make sense).
All wires looked pretty tidy.
No signs of chewing visible.
One junction box I could see - no signs of any activity.
I will get back up later and do a more thorough check. I feel like a watching brief might become an annual activity for us.

Be nicer to get the safety check done this end of the season so we know we can let it next season, but our Ts&Cs mean we can disappoint people by cancelling if we absolutely have to (fingers crossed we don't). Our sparky wasn't so keen to repeat the tests/certificate so close to the last one

Cheers all.

If the cable looks clean, dry, and not munched then dirt or water in junction boxes is the next obvious thing to look for that does not involve ant special skills or test equipment. Just some care and making sure the power is off first.

A simple voltage tester might be a good investment if you are likely to poke around things. I have one of these, but you can get a range of them from Toolstation or Screwfix as well:

Thanks - I do check for volts before doing ANY amateur electrical work
A related aside.....our electrician does appear quite keen to NOT do any changes, because he would then have to ensure the entire cottage is up to current specs....
.....although he is quite happy for me to change things where needed.

Simple example - he is not keen on sockets with USB built in - they are permanently on, will clearly add a little resistance, and (in his view!) are often cheap items subject to failing. We have three dotted about the cottage - handy for guests to plug into - but he suggested that whilst he might have them at home, he would always discourage them in a holiday cottage. I will probably change them out (anyone strongly disagree with him?).

I wonder how many people perhaps use 2 sparkys - one for the certification, one to actually do work
I type the smiling emoji, but I am semi-serious......

 

[littlespark]

A sparky that does work should always certify whatever they do….. but only the circuits they have worked on.

You can get any sparky to do an EICR, which is a report (not a certificate) on the condition of the electrics of the property, covering as many circuits as you want.

It’s not normal for one spark to do work, then a different one to certify the first ones work.



USB sockets; I used to think they were cheap and nasty… but I’ve fitted one in my own house, plus a number for customers over the last few years and never had a failure.

Thanks @littlespark
So if you did something on one part of a house, are you NOT liable for ensuring the rest of the property was brought up to current standards?
He was suggesting he would have to

No.
He only has to ensure that his work is up to current regs….

For example, when RCDs first came into the equation, many electricians added a second mini consumer unit to cover what they were adding or working on, leaving the older fuse board untouched.

I still here it all the time on site that once a sparks touches any part of the old wiring we suddenly become responsible for ALL the wiring in the property

THis is simply not the case

Its like saying a mechanic changes your break pads and is now responsible for the workings of the entire car
