I have 347 volt metal halide lighting that produces a 10 amp load what size of photocell would I need? I calculate 3470 watts of power... Am I right?

 

[TOOL_5150]

most photocells can handle 15 amps

doesn't the wattage load matter when considering the VA rating of a photocell?

Hello Bruce , Welcome to the forum..:thumbup:

What type of photo eye are you using,,,twist lock or hard wired?

Hardwired... I have a 347 volt 1000va button type photocell, but I don't think it'll work on the 10 amps I'm reading ...isn't that 3470 watts of total power??

Yes it is,you'll need either a higher wattage photo eye or a lighting contractor that is controlled by the photo eye.

Check the tork link in the post before .

that's what I was thinking. I have an extra 347 volt circuit in the junction box. I'll get a lighting contactor wth a 347v coil and feed it my extra circuit and control that circuit with my 347v 1000 va photocell... That should work. Attached is a picture of the box that I am replacing two key switches with a photocell to control the lights

Be carful with that scary voltage..:laughing:

 

[bruce1964]

Breaker will be locked off

 

[wcord]

Be careful with that scary voltage..:laughing:

None of that girlie 277/480 for us Canadians
We like our 347/600. Grows hair on your chest, or is that burns the hair off your chest:thumbsup:

I'm going to get a 2 pole 15 amp lighting contactor with a 347 volt coil. Will be controlled by photocell. Should the contacts be normally open? How much would this contactor cost?

Normally open.

Photocells typically don't have options for dry contacts. They're normally open and that's all you get

 

[bruce1964]

Thanks Harry, thought so . Contacts come in a de-energized state. Any idea of cost for a 2p 15a 347v contactor (open type) to be mounted in a box.

Phone your wholesaler for a price. You're in Canada. Every price you get off the internet will be wrong.

You can probably order a 347 volt coil ,but if you've got 120 volts there I'd use that with a twist lock photo cell set up.

When it gets dark the photo eye send power to the coil and the contacts will close and the lights will be on..:thumbup:

Bruce, you are an electrician right?

 

[bruce1964]

Yes, why??

 

[green light]

Yes, why??

No offense, but an electrician with even limited experience should know the answer to your questions. Its all pretty simple stuff. Again, dont take it the wrong way
