3phase mains boards?

[Kev2632]

Im going to be doing my very first 3phase mains board tomorrow, has anybody got some tips and advice they could give me?, and also has anybody got some photos of any 3 phase mains boards they have seen or done?

thanks

What tips do you want to see, very straight forward to be honest, nothing to add I'm afraid.

i assume you have the competence to do it, so all i can say is to dress the cables neatly, make sure all the Ns and Es are sequential, glanding and cable entries comply, take a photo of the finished job and post it. good luck.

Sure. Here's one I did earlier. It's before being made pretty btw, before the panel builders attack me. Also for advice....I'm not sure what you're worried about lol.

Thanks everybody, I'll let you know how i get on

How does the layout of the L1,L2,L3 usually go? From top to bottom? And does the neural and earths all have N1,N2,N3 or how does it correspond to the different phases?

Make notes or take pics on your phone if your unsure of anything, also take note of load balancing across the phases if there are lots of single phase circuits

no sweat. but looking at that pic. . the brown and black incoming cables do look like a pair of saggy ----.

 

[telectrix]

generally L1,L2.L3 from top to bottom on the left, then top to bottom on the right.

And make sure you don't end up putting 3 phase breakers in L2 L3 L1 or L3 L1 L2 etc, might seem obvious but I've seen it plenty.

Them loops need tidying up and use heat shrink not tape
Stuff like this is better done under supervision really, is it a like for like swap or new Install? What about the loading on the board is it split correctly?

my job tomorrow is too swap over an old 3phase board with a brand new one incorporating RCBOS instead of MCB's

I am aware lol. And the only reason the tape was there was to hold the cables while i fed them in so they didn't knock me out haha, just hadn't taken that one off yet.

Best tip I can give you is turn it off first.
