Hi

I'm moving into a new workshop but I can't figure out whether there is
3 phase already installed or not.

There are 4 large fuses as the mains comes into the building. I guess
that 3 are lives and one neutral. Could be wrong though. Two of the
lives are currently connected to for single phase metered domestic
use.

There is only metering setup for single phase though.

What is the best way to proceed? I would prefer 3 phase if possible
and within cost constraints but might go for a Transwave or similar if
the 3 phase is too expensive to set up.

Any thoughts appreciated.

TIA

but I can't figure out whether there is

Ask the local electricity board? ( Powergen?) as to what is on site according
to their records.

It sounds like 3 phase to me

I could be wrong but a fused neutral is very dangerous
and therefore unlikely.
"Two lives are connected for single phase" - again very unlikely
sounds a bit weird


It may simply be an isolating link rather than a fuse.

Yes, that's why fused neutrals in suppliers' cut-outs were banned in 1937
(under the Electricity Supply Regulations 1936).

and therefore unlikely.

There are still a few pre-1937 cut-outs still in service. Under the new
ESQC regulations suppliers have 10 years in which to replace them.
