How to connect motor?

[netblindpaul]

Is this a change over isolator, does it feed both motors, is it just an isolator?
Pics?

It looks like a normal 3 phase isolator with the feed going in top and the outgoing from bottom. The only difference is that it has loads of terminals on bottom. It feeds one motor but have 6 outgoing cables

Pictures would be very helpful if you could attach a few of the isolator and motor terminal box and even the supply where it comes from the control panel along with the contactor/overload arrangement.

It could be a manual Y/D starter (manual change over) switch.
Have you opened up "the box"?

If it is what i think it is, then it probably does not comply with legislation now, & no I don't mean BS7671.

Without more info then there is no more I can suggest, sorry.

 

[whazza22]

The casing is clear so you can see the switch and terminals. It is just an on or off switch. I have no photos at moment

What are they in contravention of , we look after several grain stores that still have these on the main fans ?

The problem is we don,t no what this isolator/starter is, no photo,no manufacturer type/series and were on page 4 . If we can,t definitive info we might as well get a mini bus and go down and have a look

 

[netblindpaul]

PUWER98 as a start, possibly others depending on the way the fans are wired.

 

[netblindpaul]

Quite benji!
Trouble is the round Robin minibus fuel would probably be more than the OP paying for someone competent to sort it for him!

Now that sounds a bloody good idea. Who’s driving the bus? The Electro-bus-ters team arrive en mass. To drunk to see what we're doing but we’ll muddle through somehow.

Is there a bar on the bus (you can see where this is going )?

 

[netblindpaul]

I like where this is going, as long as someone else is picking up the bill! :yes:

 

[topquark]

... and of course a big trunk for our tools in the bus, then we can have bus bar trunk in

**** that I want an failsafe UPS beer supply to the Bus, operation of the bus switches only to be undertaken by by sober authorised persons, (that’s ****** that idea up), When we reach county borders the supply system swaps to the local (frequency) brew.

I can see this ending in a muddy ditch at the side of a field!
