My client wants to install a 100kw solar system. He has 3 phase and 100 amp fuse installed on 200kva transformer.
Is 69kw the limit on 100 amp fuse or can he go over without a limiter fitted?
Thanks
(Thought I'd already poost this Q, but I cant see it, so I'll try again)
We have some work going on in one of our buildings atm. On of the chaps has drilled into a cable that was buried in a wall in a fairly random location, knocking out the power to one of the flats (and giving him a nasty...
I have a small mechanics shop in a rural area with no access to 3 phase. I picked up a air compressor cheap and knowing at a min. I will need a phase converter. I don't think a VFD or a static converter can do it. Is it even possible to run a 3 phase 30hp 230/460 90 amp Dual rotary screw air...
I am an enthusiastic retired engineer rebuilding a barn in France from scratch and am having problems sizing my incoming electrical cables. I have had answers from 4mm to 50mm cross section from various pages on the internet so you can understand I am a bit confused.
There are two main cables...
Hi there
I am wanting to get a 22Kw car charger installed which I believe needs 3 phase electric. I seem to recall that our house has a 3 phase supply as the previous owner had a workshop in the garden with some pretty powerful machinery. How can I tell if it does have 3 phase?
Thank you in...
So, the actual job is on a farm. I think I'll keep things simple at the moment and just ask about voltage drop. I'll come on to earthing and bonding a bit later or on another thread!
We have a 3 phase supply (100A p/phase). From supply to first barn (we'll call it Barn A) is 70 metres. For...
I am trying to understand 3 phase volt drop. I understand single phase VD.
Lets say we have a 70 meter run of 35mm, 5 core cable from the supply to the 3 phase consumer unit.
From the 3 phase consumer unit we have 1 x 16A triple pole MCB (so that's 16A per phase). which has a run of 12metres...
Hi, we are converting old farm buildings to commercial units, and as my father used to run a vacuum pump and compressor in his dairy I always assumed we were on 3 phase. However, having had an electrician check our supply, it turns out we have a dual phase supply with 100A fuses on each. Have...
Help please, this is my first post on this subject regarding solar panel / battery installation into house with 3 phase supply.
I am a DIY level person and am seeking advice to allow me to understand what to expect when engaging with installers.
I have a 3 phase domestic supply.

Hi, As a DIYer I`ve quite a bit of wiring up domestic house single phase experience but no 3 phase experience. So I have been offered a two post car lift which currently operates of off a 3 phase supply. I have a brand new single phase 3hp motor which I believe will run the lift but I assume I...
Hi everyone, each leakage question here.
I am needing to run some LED screens, professional type, not TVs. These are 500mm x 500mm panels and traditionally have 2/3mA leakage per panel.
So we generally have a 63A three phase distro with a 300 mA on input and multiple outputs protected by 30 mA...
Hi everyone,
I want to repurpose an old cable that was previously used to power a 3-phase machine. The cable is 4L1.5 micc, and I don't want to replace it unless I really have to, as the cable run is convoluted/inaccessible to say the least. It was obviously installed before many other things...
Due to an increase in load for a subman, I now need 2 phases for an outbuilding. Original design was 63a supply, but now an electric shower and another ac unit has been added due to a design error.
Questions are, can you get a 2phase mcb to fit a schnider PoN board? Are you allowed to supply 2...
How should grounding be made to a 20kVA single phase generator set feeding a domestic property via a manual change over switch? At the generator's alternator neutral is bonded to earth. The generator will be some sixty feet from the mains input box of the property fed by SWA cable. The...
Hi all,
I have been asked to install individual three-phase supplies for a band saw and table saw.
Having trouble figuring out the correct cable / breaker sizes required (I’m a marine electrical fitter and it’s been a long time since doing this sort of works).
I currently have an Eaton...
Hello,
I am hoping this is in the correct forum. To start, I acquired a film processing machine that runs on 3 phase. Now before getting the machine I fully understood it's power requirements and the cost of getting 3 phase installed at my house. I figured as processors are mostly a few...
hi guys i'm trying to get my head round the following setup
growatt TL3 5kW 3 phase string inverter 14 panels @ 395W
Spa3000 TL ac coupled controller - unless there is a alternative mcs approved one available
growatt ark 4x2.5's with bms
will i be able to draw 3 5 or 8kw with this setup please...
Ok, i am new in this forum I am looking for some enlightenment. Today I got a call from my boss, which is now in Venezuela and he is connecting a 4000W 100v power plant at his condo. The electrician he found there connected a 2 Throw Switch Knife to the circuit to split the power coming from the...
Hello all. I am trying to get 125 amps 3 phase back to a paintball field to power an electric air compressor.
I have a 3 phase 120/240v PG and E feed, 200A panel about 1300' feet away from the desired location. I have 2 transformers, so we can transform up to 480 to make the 1300' run, and...
