3 Phase board for domestic installation?

[overskilled]

Looking for a 3 phase board for a customer, older house...ideally something "aesthetically inoffensive"....i.e. something that doesn't look straight off the factory floor...
Thoughts? suggestions?

House is currently using 2 phases of a 3 phase supply into 2 separate meters, phoned the DNO to check there wasn't any reason for this...they were more surprised it hadn't been converted to a single 3 phase meter when the meters were swapped in 2009...Told to then phone supplier, whose technical team confirmed that a 3 phase meter can be fitted (with integral isolator and for free...shock of shocks..)

The DNO connections team reckon PME might be available despite it being an overhead supply, their computer system reckons yes...but requires a site visit to confirm if its possible or not....so they are coming out to do that

Yes!!! Was in a guys house once, showed me the board, no cover, thought Id check the terminals for him on ...everything, main DP Iso were threaded. Yes it was Proteus. He said

"how do I know you didn't do that"

it went downhill from there

 

[GLENNSPARK]

i come across them a lot...particularly in renteds...

they want kicking off the wall wherever their found...

hateful, spiteful things....

front covers are actually an optional extra on the proteus range
the swiss cheese busbar comes as standard though.

But what about the DBs glenn?

I've only seen one proteus locally (thankfully) but a metric ton of those horrid MEM rewireable boards...the ones where the only barrier to live points when the front cover is open to change a fuse is a frequently missing piece of plastic for cartridge fuses that no one ever had fitted seemingly...
and plenty MEM BS3871 boards ( a favourite for council sparks and local builders during the 80s and early 90s....

 

[shanky887614]

Just had a look at schneiders website...flipping heck...who wrote it.. makes not much sense...and documents missing here there and everywhere i look.....

Any one got a link to the hager board in question please?

That's quite good for schneider then.

I wont say any more or will get in trouble as we subby to them a lot

well you could say the same for the wylex metalclad range from the 70s.....where the 3036s have been replaced with 3871/60898 plug ins....and the cover has been just slung...

yep we can all argue that it meets IP4X.....but come on....

 

[Carlosfandango]

If your getting a Hager 3ph board remember the main switch has to be ordered seperatly! Got caught out with that today. Wholesaler never told me that the board comes with no mainswitch when I ordered it. Imagine my dismay today when I went to fit it!!!

Though the wylex still has a front cover of sorts...the MEM ends up with nada once the front panel is open...utterly crap design and also featuring asbestos pads in the fuses....and they ALWAYS seem to be a rats nest inside with cores cut as short as possible....I REALLY HATE those boards...
I have a severe dislike of MEM
Old contactum pre-17th boards are nearly as bad

Ooops!....yeah I noticed..cheers though mate..
Choice of main incomer depends on what the DNO reckon as to whether they can provide a PME earth or not...

One more question....lights on one phase or split between them?
The stair 2 way switching is the part that I see dangers within, someone down the line decides to swap a light switch and gets the wiring mixed up...could be an interesting light show....

most are the same mate, well I know Schneider are due to various sized main switches available.

 

[Guest55]

most brands require the switch kit ordering seperately due to the numerous cable termination & switching configurations.


and i'd put all lights on 1 phase in a house to play it safe.

 

[Carlosfandango]

Shows how many 3ph boards I buy! Poor guy in the wholesaler got an earfull this morning!!

 

[High Tower]

As Biff said, most require the main switch ordering, what i like about the hager is that the main switch comes with a big surround and a big cut out in the front cover that the surround fits into, this means that there are endless incomer options, even down to the fact that their standard board, with surround removed will take a MCCB incomer with no modifications, again really well thought out gear, even down to the blanks that clip on to the din and shroud the bus bars even when the cover is removed, means no struggling to keep the blanks in place while trying to get a 24way TPN (72 way single) cover back on

I like this big 400v labels above light switches I do ,,,,

well....i guess the old wylex boards had an asbestos bypass....did they...

now think carefully before answering....before making yourself look a complete ---....

 

[overskilled]

70s metalclad wylex boards were ceramic IIRC though not 100% on the older examples. Also rather feel a --- than feel like one lol

Was considering the following option : split the house between phases: kitchen on 1 (possibly with a local single phase CU to save someone traipsing down the corridor and up the stairs if an appliance trips in the kitchen),

Don't go installing local separate CU's, keep to a single location, unless the place is a bloody mansion that is!! lol!!

Max demand likely isn't going to top 60 amps (only 2 people living there mainly and client is currently talking about oil fired heating, and an oil fired rayburn for cooking) but has at least one electric shower on site at the moment, though the shower might get replaced by a mixer in the future...possibly..he hasn't made that decision yet.

Just two people, you'll not be seeing anywhere near 60A, you'll be lucky seeing 40A for more than a couple of minutes
