Wiring in a ABAC Genesis compressor

[stichill99]

I was wondering what is the best way to wire in this compressor . Should I use armoured cable clamped to the compressor or should I use a 4 core cable and plug it into the block which has connections for the three phases and an earth connection.

I would use YY cable, not armoured.

def flexy cable for no other reason than vibes and if u hve a fair length u can move it, asuming it's on wheels to sweep underneath.........or is sweeping a dirty word.........hahaha......

I was going to use flexy cable but was wondering about the actual connections. In the manual it says to use 6mm core which I presume is the thickness of the wire for each phase. I presume I would get flexy cable with 3 wires for the 3 phases and an earth wire for connecting to the block?

 

[Ton-up]

That's correct.

Ideally something like https://www.electriccable.co.uk/RWDyycableTECC.php
Product Code: 130017
6mm x 4Core YY Cable
Outer Sheath : PVC
Sheath Colour : Grey
Insulation : PVC
Core Colour : Grey,Brown, Black, G/Y
Conductor : Class 5 flexible plain copper
Voltage : 300/500V
Max. Operating Temperature : 70°C
Approx. Weight 0.480kgs/mtr
Overall Diameter 13.6mm

Or a HO7 rubber based cable.
As they contain fine stranded flexable copper cores it should have bootlace ferrules crimped on each end .http://cpc.farnell.com/multicomp/du...sm76NNyStj3IJIaJoyoY8-3UFSfBSRNAaAnMeEALw_wcB

There are lots of options for both the cable and ferrules but this is the sort of thing you should be looking for.

Hi Chris It is a 11kw motor,i forgot to say,would the first cable you selected be large enough? When it says in the compressor manual it requires 6mm wire,is that in total or for each phase? Cheers Andy

 

[WorkshopChris]

6mm should be fine 11kw 15hp the full load current will be around 22Amps at 415v .
But at above if you are not sure its best to get it looked over.
The most important test is that the earth has full continuity back to the point of origin.
Looking at the control pictures i can't see if this compressor has a phase failure and rotation shut down unit built in.
If it has and its wired out of phase it normally wont let you start it up.
But if it hasn't you need to find where the direction is marked(often close to the drive coupling) and very briefly power up to see its running in the correct direction.
Caution some screw and vane compressors can be damaged by incorrect rotation, make sure you find out first, if this is the case you would be well advised to seek out a compressor installation and supply company to commission or a electrician with industrial experience and the relevant test gear to confirm the phase sequence prior to applying power.
Hope this helps.

for correct rotation its wired L1 BROWN TO R ON COMP . L2 BLACK TO S ON COMP . L3 GREY TO T ON COMP

Personally I'd use H07 or H05 for this, YY isn't very tough
