Don't do much three phase and a bit of help would be helpful.On three phase when testing for pfc am I right in saying that I connect the leads to L-N and don't need the earth lead connected. As I'm not sure of putting the meter across all phase, so double the reading that is highest of the three...

Hi
I am an end user and want a 3.68kW system installed at work.
We have three phase but don't have the money to do the full 10kw job.
My installer is proposing installing a 3.68kw system and connect to only one phase.
He is using an SMA 4000TL and 16x Upsolar 230 panels
My concern is...
Next month we are installing a small 1.2 kw system (5 panels I believe), that is all that the roof can fit, but the supply is three phase. Hardly seems worth it, but it's a local authority job and I think it's more of a show home. Any ideas how to go about this, as I presume I would only be...

Im trying to work out what available power i have to play with in anticipation of some heavy machinery coming into the warehouses in the next few weeks. We...
When calculating volt drop on three phase, I can't remember if I my calculation is using the total current on all three phases or just each individual one.
So each phase at 400v is 3.8A. My calculation was 2.5mm minimum. A three phase motor run in SWA. The run is 200M underground.
Hi, I was wondering if I could get a little advice off you guys. I'm installing an three phase 8kw sauna over roughly a 50m run. The board is a typical 20-30yr old three phase commercial board with no rcd protection. I'm thinking 5 core 2.5 swa for the cable up to the sauna then into some kind...
