Excellent video as ever. Sorry to be a pedant but the title says "Contactor" and the caption at the start of the video says "Contractor". /pedant mode :)

Great vid team!

Thanks for another great explanation. Important to note what he says at 8:26 that sharing the neutrals is only for simplifying the diagram, you'd actually run separate neutrals for each circuit. If you actually only ran one back to the board (with separate circuits / breakers as shown) you would have shared or borrowed neutrals which is potentially dangerous.

@leestorey18

The contactor I have at college has terminals for a neutral as well do this mean in this case you'd have 5 neutrals coming back to the board i.e coil, connector and 3 banks of lighting?

@jollyfinequality9865

3 ай бұрын

You only have four neutrals. One for each lighting circuit which is the same as each row of lights. Plus one for the control circuit, going to A2 on the coil within the contactor. Hope that helps.

Love this Gaz!! Great video chaps...👍🏻

@@GSHElectrical It's about the attention to detail. You seem to really strive to make your teaching effective. Flashing up a photograph of the component when pointing to the board is case in point. Wiring diagrams can lose students real quick if they can't visualise it in the real world.

Awesome explanation! Thank you so much. Can we please get a explanation video on wiring a lighting control circuit including Auto Off Manual, timer, sensor and emergency lighting please

Great vid. Maybe worth mentioning that the contactor has a 240v coil in this instance. Don't want to go sticking 230v into a 24v coil. And the numbering on the contactor is indeed 1L1 3L2 5L3 2T1 4T2 6T3. Normally open or normally closed. And the additional use of the auxiliary contacts 13-14, 21-22 could be used as an indication lamp that the circuit is energised. Can't wait for the practical Vid.

Great detailed video just what I've been waiting for, heating/boiler wiring next ? Also how do you select rating of contactors ?

Thank you so much brother please help me with this knowledge I'm said from Zanziber in Tanzania

That's the perfect way to connect a contactor in three phase

Fantastic explanation. Those contactors do go funky sometimes and make a buzzing, if they do a thermal camera can pick up issues early. Also was that Thor!?

Love it

Not just for lighting either. I recently set up a situation where the lighting circuit (on a timed switch) ran the lights plus the coil side of the contactor and the socket circuit ran on a radial through the contactor. This meant that when the lights timed out and went off, so did the sockets, thereby guaranteeing nothing could be left on unattended in the area.

Good job 👍 I carry out commercial maintenance one problem I come across regularly is “bms being installed onto non essential distribution boards ie 70% lighting in a large commercial premises. When these alterations have been made the provision for a permanent supply for emergency lighting has been overlooked! On the plus side no pun intended generates more work for me.

tomorichard Thompson that’s the perfect solution for the above scenario 👍 unfortunately not the case for the last two I have had to rectify as a bms had been added to an existing installation. The company/contractor split the existing lighting distribution board so they could reduce lighting outside of trading hours. 70% board was operational during trading hours 30% board 24/7. Unfortunately 70% board had emergency lighting feeds and there solution to install 100a 4pole contactor below distribution board resulted in emergency luminaries discharging every night. Live and learn😂👍🎅

Thanks 4 the wonderful explaining. What about wires sizes please?

Great video. Not a criticism, but I would also clarify that in large buildings like that the lighting isn't wired in straight lines as shown in the diagram. Each of the phases L1, L2 and L3 (or R,Y and B) should be spread across the three lighting banks.

Great vid. But it would be fantastic to see the design calculations, for a given installation :-)

@richardprideaux5185

Another thing worth mentioning is that the contactor illustrated by Matt, is a N/O (normally open) contactor.

Good video! Very helpful ! One question - How you choose to use 3 single pole breaker , instead of 1 three pole breaker? Thank you! 🎉😊

The best explanations for a contactor.Can I add a photo cell into this application.?And would it be spliced together whit the switches?Or difrent wireing need to be applied? (In series or in parallel) Thanks and cheers guys.

I wired up a contactor to switch two supplies (a.c. mains and a.c. mains generated by solar PV) to one load - my hot water cylinder. So when the sun is shining one set of contacts supplies electric from the sun to the cylinder. When it's dark, a mains spur activates the coil and switches the a.c. mains on to the h/w cylinder, so the one circuit 'makes' and the other 'breaks'. It works fine and is another example of switching high current (well, 12 amps, high for domestic I suppose). I will blow myself up one day, but I just cannot get an electrician for love nor money where I live. :) :)

love the video, how ever in Australia we need RCBO'S for any circuit under 40amps. How would you use RCBOs in this ?

totally cleared things up for me in understanding the beauty of contactors but does 2 way mean 3 way and are the "strappers" travelers and why is "4 way" written in the panel drawing? please explain 4 way in a 3 phase panel? thank you

We use contactors alot in the railway. We use 110v to turn on 898v motors

hi guys, enjoying the videos! please can you add a link to the video where your in the workshop connecting up, i cant seem to find it?

thank you fr this video but my question is what if you're using 3 contactors how you gonna wire yr A1

Great explanation. Regarding sizing of the contactor itself,.do you size it to the full load capacity? In this example a 60A three pole contactor? Thank you guys, much love from Australia

Brilliant video guys, can i ask 2 questions please, first what should be the rating of the contactor based on the load of all the lights? Second why did you use individual mcbs instead of a three phase mcb? Thanks

Very good explanation of contractor and workings of the coil

Hi. Thanks for the positive comment Gaz 👍

Just one thing, what’s the amps on the contactor? By the way that was awesome. Keep up the good work.. cheers.

The live that goes into the 10amp switch did it come from a separate breaker or... Im abit lost there. Rest i understand. Thank you

Nice idea good U didn't tell us the size of the wire to be used for incoming line of the contact ore u select 20 amps fuse ,

would you recommend wiring the lights in a 2.5 now because of load on each circuit?

So when you bring the 3 phase conductors from the panel to the contractor, I understand where the hots go, but where abouts do you tie in the neutrals? Do all the neutrals get soldered together or do they land somewhere on the contractor?
