Question about Prime 10 Amp Circuit Breaker

1 Answer

Photocell and circuit breaker

I bought a Steinel 3000 photocell. In instructions it says it needs to be installed next to 10amp circuit breaker. Is there a need to buy a separate box or will the fuse board do the same job?

    Hi,

    Thanks for reply! Just to clarify, would 3amp fused switch do the same job (the whole system is on 30amp circuit breaker)?

Hi, Here is my clarification of the instructions for you. The photocell must be protected by at least a 10 amp circuit breaker. The photocell may be installed next to the light fixture. ( not the breaker). Good Luck, this should Fixya!

    Hi, The specs call for a 10 amp minimum, usually this is to allow for the 1000W switching capability without knowing the exact current draw. Since I do not know what you are switching I would only be guessing at your success with not constantly blowing the 3 amp fuse. If you have several fuses you can certainly try it, if it doesn't work, I believe a 10 amp fused switch may be less expensive than adding new wiring and breaker. Good Luck to you!

Place tape over photocell lens, and flash switch off-on. Did the light come on?If you know how - remove the photocell from the circuit and see if the light works. If the light works, then the photocell is probably bad. Check power from switch to photocell with test meter.

You have 120volt photocell.

Wiring sounds correct.
Lights are on all the time, even in daylight.
How is the power by-passing the photocell shut-off?
Disconnect ground wire to make sure there is not a ground fault causing circuit to complete on ground wire.
Otherwise the photocell might be bad.

I would like a wiring diagram for an outdoor receptacle controlled by a photocell. Photo cell has 1 each black wire, red wire and white wire.


If I understand correctly, you want to add a photocell to existing receptacle.

Start by looking at receptacle:
Receptacle has 3 different colored screws.
Green screw for bare ground wire
Brass screws with black Hot wire connected.
Silver screws with white Neutral wire.

How to wire photocell to receptacle.
Remove black Hot wire off of brass screw and connect black wire to photocell-black wire. This will power the photocell switch.
Connect photocell-red wire to brass screw on receptacle. This will turn receptacle on-off whenever photocell switch turns on-off.
Connect photocell-white wire to silver screw, and this will complete circuit to photocell switch so the switch is able to operate.
All white Neutral wires are connected to silver screws.

1) If this is new installation: Check wiring.
Black to Hot from breaker.
White to Neutral from breaker box.
Red to Load (light)

Neutral wire is necessary to operate photoeye.

2) If installation worked at one time but doesn't work now, then photocell is bad.
Or if photocell is new, they arrive defective sometimes.
Proof is your black-tape test.
Buy new photocell from Home Center electric department, or lighting department and connect wiring as described above.

Wireing diagram do not no were thay go three wires


K4221C photo cell page at Intermatic:
http://www.intermatic.com/products/photo%20controls/commercial%20%20industrial/stem%20%20swivel%20mount%20-%20thermal%20type.aspx

Photocell has black, white and red wires on photocell.
Black goes to Hot from breaker.
White goes to Neutral from breaker box
Red goes to Load (light)

Electricians don't guess, they test.
You should have one wire coming from breaker box, and another set of wires going to light.
Separate wires for testing.
Since you are outdoors, stand on dry boards and tape tester leads to wood sticks to keep hands away from power.
Turn power ON
Test each wire to bare ground wire.
Tester lights up on hot wire. This wire should be black.
Hot wire connects to photocell black

Hot is identified.
Test Hot wire to all wires except bare ground.
Tester lights up on neutral. This wire should be white.
Neutral wire connects to photocell white

Now the other cable goes to Load. This cable has a black and white wire.
Connect photocell red to black Load wire
Connect white Load wire to Neutral, along with photocell white.

Ground wires are twisted together.

When we start the heater run fine for 30 seconds then trips reset


You state after the heater starts it "run fine" then trips the breaker. I assume when you write "run fine" you mean it has no sputter or obnoxious odor or eye burning sensation and it should not be shutting down.

If this is the case either the SAFETY CONTROL (reset) or the photocell is bad. Test the photocell.

If it passes replace the SAFETY CONTROL and/or the photocell.

Lights do not come on at all. Breaker is not tripped. How do I test photocell?


to test the photocell you will need a tester, a basic pen tester will do fine, you just need to make sure that power is going where it needs to, when it needs to. first you will need to identify the feed with the tester, this is the wire that should have power to it as long as the breaker is on. once you know which is the feed, the other should be your switch leg. after you have identified the switch leg, cover the eye of the photocell, it may take a few minutes before the switch activates, I would wait up to 5 min. but no longer than that, if you are not getting power past the photocell at this point, then it is most likely bad.

Lights are on in daylight


if it is a two wire photo cell ( as opposed to a three wire) then the load on the cell is very important check the instructions lots of load sensative photo cells won't work with low voltage lighting or led lights, good luck

Torpedo heater runs for a minute or two then the breaker trips.


You can test the photocell by hooking up a ohm meter on thr rx1k scale. Photo cell should be out of the heater.Hold photocell up to a light bulb,with light on resistance of photocell should drop to 0 to 100 ohms.Holding finger over the photcell and blocking the light the resistance should go up to the maximum resistance
