100A DP isolator for SWA. Any recommendations?

[f0rmula]

I'm installing a consumer unit in a new location, about 4m from the existing meter/cu. The meter tails won't reach. I'm planning to fit a 100A DP isolator near the existing meter, and use 25mm 3core SWA to supply the new CU until the transport/meter people can be arranged to move the service head and meter.

Can anyone recommend a cheap and cheerful 100A DP isolator? I'm loath to spend too much on it as it'll only be in use for a couple of months. The following seems ok, but how easy will it be to terminate 25mm SWA in there? http://www.tlc-direct.co.uk/Products/WYREC2S.html

Also, I was also considering picking up the 25mm 3core SWA off of ebay... There seem to be pre-used lengths reasonably cheap. On a scale of 1 (good) to 10 (bad), feel free to rate this idea.

If it's only temporary, why not just use a 5metre length of meter tail?

Your plan has some difficulties:
The RC2 is not suitable for SWA. It is made for meter tails.
The SWA will need to be properly terminated. You'll need something like a metal galvanised box at each end to fit the gland.

Then the resulting L&N conductors will only be single insulated as they transition from the adaptable box to the REC2.
How would you achieve double insulation?

If you want/need to use SWA of that kind of size then you really require a sturdy metal enclosure to gland it to.

As for buying electrical stuff used you are taking the same risk as when you buy anything used. That you don't know how the previous owners used/abused it.
