3 phase power connection upgrade

Martin098 · Jan 17, 2023

Hi we want to upgrade our single phase power to 3 phase power at our commercial premises. 3 phase is next door just beside our doors. We need 67 kv of power for our sunbed shop. Will electrical supplier need to put new cable or they can connect us to existing one ?

Pretty sure your supplier will need to answer this one. Have you asked?

The answer to this is as simple as picking up the phone to your energy provider and/or DNO and having them come out, do a survey and prepare you a quote. There are literally just way too many variables and unknowns.

BTW.... 60-70kW sounds an awful lot for a bunch of UV sunbeds, are you sure this has been calculated correctly?

That's a hell of a lot of UV being absorbed into people's skins.

According to the clip below 67kw would only be 7 sunbeds,

No wonder we've got energy problems. 25A continuous for a bitcoin miner, god knows how many multi-kw outdoor patio heaters, spa tuns bubbling away, half a megawatt (ok, I'm exaggerating there) toasting people's skin.
