I've been asked my opinion on an installation and found that a company have installed a 3 phase supply, outdoors, open to the elements. They have crimped the cables and wrapped them in electrical tape. I'm going to attach photographs if I can figure it out, but I cannot see how electrical tape is providing IP protection and I think it's a cowboy installation? I'd be interested to hear your thoughts, since it's cable tied to a copper water pipe? What would you advise the company do about it, because I feel that a 3 phase supply should be terminated in an IP rated box outdoors and not crimped and taped?

either a pratley joint box or suitable ip rated plastic box and CW glands, sound rough as a badgers.

ps if you were going for the ip box invest in Retech magic gell also. all out outdoors joint boxes gets this

A rhetorical question that should not need to be asked by an initiate.

On the face of it it does sound rough although probably not that much of an issue if self-amalgamating tape has been used.

Crimps are a joint, and I doubt that tape (even self amalgamating) (possibly not heatshrink sleeving for that matter either) would provide a non-combustible enclosure demanded by 526.5 if a conventional accessory or equipment enclosure isn't used.

Attaching Images:

Host the images on a suitable website such as Photobucket.

Click on <Reply> under your original message. A new window should open.

Across the top are a series of Icons, one looks like a small mountain. Click on that one to insert an image.

When the dialogue box opens, go to te hosted images and get the URL something like: http: // i2.photobucket.com/albums/ *********.jpg

Paste that into the dialogue box and OK it. The URL will appear in the message box. Repeat for other images, inserting text as required ...


<Preview> to check, then <Reply to topic>

We get this nonsense all the time, go to the mains position, locate the fuses, and pull them. Take photographs? You wont need to now.

Sounds dreadful. I Wonder what sizes and type of crimps were used. Insulated type etc ?
I doubt electrical tape can only be removed by destruction.

That is the case with self-amalgamating tape!
