Shed/workshop queries for tradies

[Akzle]

electricunts:
shed runs as spur off main building. Breaker inside house is 20a (with earth leak (dipole?) rcd thing), shed board has 2x 15a gpo and 1x 5a lighting circuit. 40a total aye
House board has 140a total on the face of it, with the 'main' being 3gang 240/415
this sounds like three phase, which might come in handy in the shed, but 'slike its only one phase going to, yea?
So, can i put a 40 or 50a breaker inside house, as by the time im making noise with tools im over 20a, and walking over and flipping itd be a cunt.
Yes/no?
2, can i drag full 3 phase to the shed? What is code requirement re ducting/poles/conduit?
Then, presumably i can tap off single phase too?

Concrete finisher cunts:
the floor is 6-10 slabs jigsawed together. 80sq meters.
Total variation over 30mm, chips, holes etc. Plus oil stains and shit.
Can i hit it with leveller compound? (any prep?) Am i better boxing up and tying another (4") slab on top? Or grinding down 5-10?
As much as id love to epox it, its probably going to have to deal with mere paint. Only one bay will have trolley jack abusing it as i plan on a gantry. The rest is basically workshop floor, no doubt the odd oil or coolant spill but generally just walked on...

also, im at the end of the powerlines in the wops. Theres an 8?kva transformer that supplies 3 farm houses and another shed already.
Got a stack load more lifestylers invading further toward main feed in end so dont know if this is likely to fuck up capacity?

[Akzle]

also, the power box in the shed is some melamine shit, spose i need a proper din one yeah?

the breaker is there to protect the cable, depends on what size cable is running over as to what size protection it needs

[paturoa]

Basically circuit breakers / fuses protect the cable. So find out what size the cable is to the shed. There are simple tables for cct breaker size to cable size. Ignore the part about the length, that is for selecting the size of the cable you need in the first place.

Edit: Wot he said above.

Ah melamine...drilling old switchboards bring back memories.
Get a Registered Sparkie to do it so they don't have to quit the industry and work for Corporates like me.
You get a proper job and COC too. :lol:
Or get that old Post Office workshops bloke from Wanganui to do it.:woohoo:

looking inside the melamine box... Big.
Defnitly big.
To my untrained eye, id run 30a with no drop. Looks slightly smaller than demarc/kwh meter cabling. But this shits probably 60 years old... So..?
That suggests running new cableh?

got a camera? if ya have use the fucking thing, are there any crimp lugs on either end of the cable? wont be on the phase, posibbly nuetral at shed end, this may have a stamping on telling you cable size

bump!

Hey, anyone wanna buy a hyosung?

thats why no one's dumb enough to fuken buy them. Oh. Wait on...

house:
demarc -> fuse panel ->meter ->??

The treble breaker in the box says
63a 240/415v its a 3 gang.
Is that 63a at 415? (acros 3 phases?) or 63a/phase?
Old wire in the roof is 7x ~2mm conductors...

weeeel. Guess whosa fuken moron today.
Only 2 phases at the house. (took the covers off shit. Should problya done that sooner)
:brickwall:

so, someone hook me up with a >2kw single phase motor.

Also, got the sparkie out, reckons 6mm cable good for 32A. (also reckons 3grand to put 3 phase on deck. Fkuc!)
Gonna set some shit on fire!

inverter....

[Akzle]

inverter....

as much as id love a 30a rpc. No.
$$!
And not the most efficient in terms of power used v wasted. Might as well use the motor to drive the machine, rather than generate to drive the next motor to drive the machines.

Havent dug too far into vfds as price vs ease makes the single phase motor the best option afaik...

But if you have one going cheap or free?

[Akzle]

more of this. since i've knocked a few things off the top of the to-do list.

so. existing demarc -> main panel, 2ph
i want to add demarc (fork)- shed sub panel 2ph - RPC (seems the bestest bet) - 3ph panel - all shed power (lights and power balanced across 3phases)

my main question, now, is - do i need to drag neutral and earth over from the demarc, or can i whang a new earth in close to the shed in good ground?


and also, but not so much, if i run fluro tubes on two different phases, they're safe to work on spinny woosh-woosh machines, being that the 50hz flicker cancel each other out, right?

chur guy. chur.

You could try engaging a professional and pay them for their hard earned knowledge and expertise and save yourself some money and possibly your life! :scratch:

Just readin and thinkin out loud like ... nothin serious or anyfing! :rolleyes:

(i'll be getting the local sparkie to come and live it up, just want to do as much of the wiring meself to save my stores of jewgold)

A) Hey you really know how to hurt a guy! :crybaby:

B) Fair nough! :niceone:

[mossy1200]

I have been a sparky since the 80s.

My advice is you need to find a sparky to do the work.
Preferably one who speaks gibberish cause I don't know what the fork your talking about
