3 phase question

[Badged01]

The mystery solved ........

theres a sub feed from house cu to a workshop single phase to power lights sockets

and yes most definately .......

Seems somebody went about the initial job in a strange sort of way....

- - - Updated - - -

And further intrigue to the plot ........

It looks like there was an original single phase supply , and then had 3 phase installed at a latter date, you see this a lot ,,,

Then they should have binned it and installed 3ph and N...but we might as well have a **** up.

OK.

so i distinctly remember asking if a phase rotation had been carried out here

as
it is:

black --l1 fuse
red-- l2 fuse
blue--l3 fuse

and theres no identification rings then its a contravention of 514.3

saturn's got all the rings: jupiter's got all the moons:and i ate all the pies. so there.

A man after my own heart, quoting regs pulls the chicks ......

Probably didn't want any disturbance to the lighting and power with the machines starting

PV won't comply after he installs it either by the description here.

looks like a diy job to me the 3phase
BUT i wont be using the 3ph db
i shall be using the single phase board i will be making it a 6 way instead if the 3 way installed via 10 mm feed

1x 32 ring
1 x 6 amp lights
1 x 20amp to paint booth
3 x 16amps for pv

 

[netblindpaul]

See what I mean!

 

[Badged01]

See what I mean!

Nope, but Im sure you can enlighten us .......

 

[netblindpaul]

It seems 3ph PV system is being connected to 3x16A mcb's in a 1ph DB, which is not at the origin of the installation, thus downstream of some protective devices, thus negating the function of said protective devices, with regard to ADS and relying upon the PV inverter to undertake the disconnection.

What else do you want?

Do you think it's OK to skew the supply by 48A of PV? infeeeding to a single phase.
Will the DNO OK this, will it be OK, is it OK, what more.

I despair, I really do.

I really will not comment any more on this thread, so don't even bother to try to get me to.

It took some teasing out but we eventually got there ..... now even I'm enlightened
