External telephone line junction box.
What is the approved method or junction box for joining the external phone cable - i.e. under the eaves, between the drop wire and the house wiring? And where do I get one?. I need tidy up the choc block + tape splice that I did following the builder pulling the drop wire bracket off the facia with a JCB.

Re: junction box
Isn't all the external wiring BT's responsibility?

Re: junction box
As has been said anything before the Master Socket is BT's domain.
As it's been "DIY'd" though, you may get it in the neck if you admit it was you that did it and incur a charge if you call them in. If you want to continue the DIY approach I'd use a weatherproof ABS box box and join with gel crimps inside it. I did this inside the "official" BT box outside as the screw terminals and wiring had turned a pretty blue colour and the screws had corroded themselves into the terminal block. There had been loads of past DIY activity in there as well (before my time !). |
Re: junction box
I got and fitted one of these boxes from 'Comtec' or somesuch (can't remember now) back in 2012, but available here on Bristol Communications and Electrical.
https://www.bcedirect.co.uk/products...side-joint-box They also do the dropwire and PJ connectors. I had to do this because the builders doing up the house cut the original dropwire! Never had an issue with BT. Strictly speaking, there could be, but I've also had the Openreach lot around to do jobs and they willingly left me to finish them (just nipping up a few connections, etc...). I suppose this allowed them to make up time before moving to their computer-dictated next job. |

Yes, I suspect that Openreach Engineers have more to worry about than forensically examining installations in these time restricted days. You can get most of their kit on eBay and a workmanlike installation is unlikely to attract attention. Pigs ears may be different of course, but like for like should be OK. It's only two wires after all!

Re: External telephone line junction box.
Easy. You loosen the terminals and then report a fault. How are you supposed to know what someone in the past has done? Not your problem!

Re: External telephone line junction box.
I would go for replacement of the "temporary" fix with the above-mentioned box and just keep quiet, rather than contacting the "powers that be" with a fictionalised account.
By the way, don't forget that the box is designed to have cables entering from below with a loop from which rain can drip away from the junction, so I hope you have enough slack in yours. |

He made a very neat installation, took his time, and even fitted a loop into the wire where it left the wall anchor. Intrigued, I asked him why he gave the job the attention he did. 'It's because there are random inspections', he said. The quality of the installations had certainly improved a hundredfold since the bad old days of burying a DP feeder cable six inches beneath a field across its width rather than keeping to the edges (another story)! That was in 1996. I don't know if 'random inspections' are still carried out as there has been a lot of staff turnover and changes in working practice since then, in particular with the employment of contractors. |

When my wife had a second line installed for her work, Openreach used this cylindrical plastic contraption.
I imagine it uses screw terminals instead/as well as IDC, because of the mixture of wire types. Attachment 179550 The 2pr from the pole enters on the RHS the "new line" (long since disconnected) is the lower cable, and the existing CCS "figure eight" is the one still in use, it's only a couple of metres long until it gets to the linebox in the house, but is well past its sell-by date, although gives no trouble. When I moved into this house in the mid '70s one of my first DIY jobs was to remove two runs of unsightly cable on the front of the house that served a bedroom phone extension. The cable turned out to be lead-sheathed twin, that looked a bit like modern 1mm or 1.5mm twin & earth mains cable. |

Re: External telephone line junction box.
be aware that Openreach now try to charge for every fault on the dropwire as a mater of course but I might have one of their boxes in my junk box if so you can have it for postage

Re: External telephone line junction box.
They can't. Anything north of the NTE is Openreach liability.

Re: External telephone line junction box.
When I reported a fault on my son's BT line last year, the standard recorded message intimated that there would be a charge for fixing any damage to the overhead line inside your property boundary. In his case, it wasn't an issue.

Re: External telephone line junction box.
The use of iron (actually I think it was steel) coated copper for drop wire had nothing to do with a shortage of copper. It was done to impart strength to what would otherwise been comparatively small diameter cadmium copper wire. Before the advent of drop wire two bare copper wires weighing 40 pounds per mile were run from the distribution pole to the premises.
It pre-dates the copper shortage which came about when Rhodesia unilaterally declared independence from the UK in November 1965. Sanctions meant that Zambian cooper could no longer be shipped via Rhodesia and South Africa. I believe drop wire was introduced to permit speedier installation of domestic telephones by "One Man Installers". Previous to that an overhead gang made up of four men would have installed the drop using bare copper wire. |

I have found the gel seal in my box of bits you will need the crimps but the seal if yours for postage

Iron or steel core, what happened with mine is the water got in, rotted away the core leaving two 'hollows' of copper plate and nothing in the middle! |

When I started my apprenticeship in 1967 the use of drop wire for new installations or replacements was almost universal. However the training schools (Bletchley Park in my case) still taught the installation of bare copper drops and then cable from the insulator to the protector, in addition to the use of drop wire. A case of overlapping syllabuses like valves and transistors. |
