Good morning,
So I’m working on an existing 3 phase solar system and the customer wants a way to use the huge mass of exported solar on their pool.
So currently looking at possibly using MyEnergi Eddi’s or something similar to power a 3 phase heater element (probably split into 3 single...
Hi I have a question hoping I can get some help. I wanted to know if there is a 400V 3 phase supply (A/A/A) terminated on the primary side of a TMD breaker can you take 2 phases from the secondary side of the breaker (A/A) to create a 400V supply only excluding E/N and use to power up your...
I didn't get a picture so will have to wait until I go back again but I've done a crude drawing of what was there.
Its in a commercial set up with a poly-phase meter, the distribution board and switchgear were all quite old but the meter looked fairly new, it was the usualll 3 phase in and 3...
I'd appreciate a quick sanity check, thanks in advance:
New circuit for a 3 phase cooker, in a community centre (run by a charity). Total load 16.5kW: L1 27A, L2 27A, L3 15A. (6kW oven, 6 hotplates: 3x 2kW, 3x 1.5kW).
Commercial setting so no diversity: 3x 32A OCPD. (?)
TN-C-S, so Zs...
I have an old Migatronic Automig X 200 welder configured as 380V 3-phase unit.
Migatronic for spec.
I have a 220V 3-phase point in my garage, but that does not work well, obviously.
What would be the best option to get this welder to work?
Would it be possible to rewire it so it can work on my...
Hi all..
Bit of a nightmare afternoon,, testing a caravan park TP&N panel board IR testing while board isolated before returning power (merlin gerin panel board) over the next 30 mins customers on park are reporting loud bangs inside some of there vans, boilers and electric fireplaces (with...
Hi all i have asked a electrician about the mic level i would need to power the following machines a 45kva cnc mill, a 32kva cnc mill and a 60 kva cnc lathe but have been unable to get an answer. I would like to get the 45kva mill and the 32kva mill sorted first it will be 6-12 months before i...
Hi
Looking at a job currently adding a 3 phase solar installation but the distribution board is full obviously a new board is the best option but if the customer isn't interested in this what do people usually do? Add a small 3 phase board and use Henley blocks, I've never seen this done but I...
Hi, leading on from my question the other day about running the 3 phase compressor off my 8.5kW generator I have since got my hands on a 240v to 3 phase converter. My question being the 3 phase output from the converter has only 4 wires/ seperatly cores coming out where as my compressor...
I have above mentioned breaker which does not have any markings to show which is the neutral pathway, I wish to fit it directly above a 3 phase 4 way surge protector which has its neutral on the right hand side and so would ideally want to connect the neutral above it on the right hand side of...
Hi!
Once you've calculated the voltage drop in Volts - you divide by 400V for three phase right?
For example: three phase 30kW appliance, 10mm 90 degree SWA, 45 meter run.
30,000/sqrt3/400 = 43.3A = Ib
from the table 4E4B, a 10mm cable gives 4.7
So then 43.3 x 4.7 x the 45 meter run gives =...
Gday lads. Have a question about a 3 phase shed feed.
I have a roll on 16mm2, 3 core and earth orange circular. Can I run a 16mm2 SDI neutral in the same conduit.
And anything I need to comply with in SNWR.
3 phase Will be for shed and mainly to run welder
My daughter lives in a flat in London in converted circa 1900 5 storey terrace in Bethnal Green. She is considering getting a Stiebel Eltron instant water heater fitted, however if she wants one that is powerful enough for a bath, she needs 3 phase. Are flats like houses in that each flat is on...
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
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...
Where do people record the Ze & PFC of a 3 phase installation, if there is say 10m of 25mm tails between the 4 pole isolator (next to the meter) and the 3 phase distribution board, therefore some (though negligible) resistance?
Do you tend to test at the origin, and record that result, or do...
Need to source Type B 3-phase distribution & 3P MCBs for EVSE, 1P RCBOs etc. so my sparky can install. A 6-way 3P board will suffice. Wondering what the general concensus is.
Say, Contactum at the cheaper end vs Schneider Acti9 at the upper end.
Drawn towards the Schneider as super neat...
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...
