Literally, a circuit is the course that permits electricity to flow. The Language of Circuitry First, allow s check out some of terms that you will have to recognize: Voltage: Gauged in volts V , voltage is the stress or force of electricity. This is usually provided by a battery such as a 9V battery or keys electrical energy, the electrical outlets in your house run at V. Electrical outlets in various other countries operate at a different voltage, which is why you need a converter when taking a trip.

California Title 24 Compliant Intermatic Photo Controls provide dusk-to-dawn control of street, parking lot, billboard and security lighting. Mounting types include fixed position mounting, stem mounting and twist lock. With so many different options, Intermatic and Green Electrical Supply have the right Photo Control sensors for your application. On the other hand, a compact fluorescent CFL requires a non-electronic, or mechanical control. The problem using any control device with CFLs is voltage leak.
Some photo controls actually leak a small amount of electrical current in the off position. The best way to test if your existing photocell is compatible with CFLs is to measure the voltage at the socket when the sun is shining brightly - a digital meter is required.
The voltage should be 0. These types of dusk-to-dawn sensors work well with CFLs because they are either totally on or off and without current leak.

They operate on volt, turn on in the evening when light levels reach footcandles and turn off in the morning when light level readings reach footcandles.
If the photo control is installed on the south side of a building, face the photocell east or west or point the photo control down toward the ground. The best direction to face the photo control is north. Do not face the photocell where it can see artificial light. Light from windows, signs, street lights, etc.
The photo control should not be positioned so that it sees the light it is controlling or reflected light - like off of your white siding or white painted soffit overhang. These conditions will cause the light to cycle on and off. The photo control must be installed in an approved weatherproof box. Do not attempt to caulk around the wires.
When you are testing the photocell, be sure to turn on the power load will come on and wait up to 5 minutes for the photocell to switch load off. For further testing cover the photo control completely with black tape or another dark material to simulate night conditions.
If you cant cover the control with tape, try covering the photo control with the shipping carton to simulate night conditions. Related Products.
