Default 415V sticker in household meter box

My father has said he has a 415V sticker on the feed into his meter box.
From what he's told me there is the normal arrangement of master fuse,
meter, then into the house to the consumer unit. The house was built in
1985ish and is detached. I've never seen inside the meterbox myself, only
the consumer unit, which looked like a normal run of the mill row of
circuit breakers with one master at the end, 100A. If there were three
phases in the meterbox I'd expect his description to include a lot more.
Now the previous owner did have an ironwork hobby with "high powered
equipment", but he was a very frugal sort and I doubt he would have got
three phases installed if he didn't absolutely have to - mind you I
believe he was the first owner of the house and designed it himself, so
maybe it's just as cheap to get three phases when building the property?
The reason this has come up is they've just had a 10kW electric shower
fitted (used to run from the hot water tank, but that one was old and
leaky) and are considering replacing their ageing oil boiler with an
electric one, which the electrician fitting the shower warned would
require a relay to switch off the boiler so it didn't run at the same time
as the shower as he'd run out of juice. When he saw 415V he was wondering
if he infact had more phases available.


That's a fairly mundane story, god knows what response you expect, there
isn't even a question. I'm confident that your higher degree will solve any
possible issue.
Not to worry though, Wodprick will surely be along to play, shortly.
Lets have a really long, stupid thread, for a change.

Maybe you could hurl yourself at the 3 phase busbars? Go on, give it a go,
you know you want to.
