240v industrial range???

[biggal5]

Hi All,

I am hoping someone can help me as i am abit confused as to how to connect up a panel saw? My friend has bought a table/panel saw that has got the 240v industrial 16A plug (blue and grey plug similar to the 110v site range). Also the thick flex connected to it has 2.5mm on it so I'm guessing that's the flex size. A little confused as to why the flex is so thick tho?

The information on the side reads : Rating: Industrial
Main motor power: 240v 50Hz 2.2kw
Phase: 1

He wants to install it in his garage which has a standard garage consumer box with x2 mcbs: 32 for skts & 6 for lights, no spares.

Is it ok to spur off the sockets circuit and connect a 16A panel mounted socket outlet? I am a little baffled as the weight of the thing is ridiculous and it doesn't seem right that it can just be connected to a garage unit, even though the power output etc seems to say it's ok?? (or am I missing something??)

It does say 2P+E on the plug however just 1 phase on the side? It's an axminster plus P30 panel saw.

Please can someone help me. It's the first time I've come about something like this? Although just got my bookwork passed recently. Many many thanks.

No not really, it may trip a B32, & I don't want to be coming across on a fault on the machine as I don't know where you are, just to find it due to inadequate supplies as this gets complicated.
You need to put this on a C or D, 16, this would need to be checked, on its own dedicated circuit.
However, it may or may not require a 300mA or a 30mA RCD also.
I don't have the P30 info to hand, amongst other possible requirements.
Change the "garage" CU for a more suitable one and, ensure that the supply is adequate for the additional load as per brb?

Oh, Sorry for the baptism of fire, it is all meant in the kindest way, and, Welcome To The Forum.

Fantastic, great help. thank you very much sir. I said I would install it this weekend so wasn't sure if I'd get a response posting so late...

when you say a C or D 16 would need to be checked do you mean from the panel saw? He bought it secondhand so hasn't got the manual either!

The incoming main switch is RCD protected so hope it doesn't keep tripping that! Also changing the CU for a more suitable one just so that it has that separate space for the breaker? Also is standard twin+E cable suitable?

Many many thanks netblindpaul... (this forum is amazing for info)

The C or D 16A breaker for the dedicated saw circuit would be at the garage CU, which he has advised you to change for a 3 way, giving you B32A, C/D16A, B6A configuration. You'll have to see if the 30mA RCD holds in. Just make sure that the supply to the garage CU is suitable for the new loading. It probably will be if it was suitably sized for the present loading. The demand within this garage, is going to be quite low overall.

Electrically inspect and test the saw out for your friend, before connecting it up to the supply, as you never know what your buying second hand.

i'd be inclined to use a 20A C type MCB for the machine. 2.5mm cable would suffice. ( clipped direct or , preferably, in trunking/ conduit to protect from mechanical damage).

Not much info on their website, load is given as 2.2kW.

There are a couple of general H&S advisory notices for the machine as well, in the downloads section: Buy Axminster Plus P30 Panel Saws from Axminster, fast delivery for the UK

Can't find a full user manual on their site though .

Great, thanks very much everyone... Makes me alot more confident now. Great help.

 

[i=p/u]

only a baby saw at 2.2kw, , you could stick it on a plug top....

How long would the fuse last?

 

[i=p/u]

who said fuse i was thinking hairclip

 

[i=p/u]

oj doesnt say inrush current anywhere tho

 

[netblindpaul]

biggal,
I can ask for a user manual for your friend and see what comes through if you like?

 

[netblindpaul]

i'd be inclined to use a 20A C type MCB for the machine. 2.5mm cable would suffice. ( clipped direct or , preferably, in trunking/ conduit to protect from mechanical damage).

tel,
Whilst I appreciate your point, Ohm only gives 10A approx.
Also I disagree with putting a breaker on larger than the current carrying capacity of the equipment in the circuit, i.e. 16A 60309, for me max breaker = 16A.
Yes I am pedantic.
I would go D if C was not capable rather than 20A.
TBH.



I would also assess the original cct loading etc. and check the csa of the final cct depending on the run.

 

[Inteificio]

+1 on what paul said.

Were you seriously suggesting upping the rating to take in to account inrush current?
I would be surprised if a type C would trip, but if it does go D, don't up the rating.
