All light fixtures or pole assemblies require proper evaluation to ensure that the structural integrity of the assembly is not compromised when applied in specific wind conditions. Therefore, the basis for pole selection in this catalog is total weight and effective projected area, EPA (ft sq), shown on the individual pole catalog pages. Determination of maximum EPA (ft sq) and weight loading must include all light fixtures, bracketry, signs, decoration, overhead wire or other equipment that will be mounted to the subject pole. Light fixture EPA (ft sq) and weight data are found on their respective product pages.
The total effective projected area of the light fixtures and brackets shall not exceed the EPA (ft sq) listed for the pole selected at a given wind velocity. Poles that are to be located in areas of known abnormal conditions will require special consideration. Please consult factory if poles are required for Florida Building Code or other special wind load requirements. The wind map page gives the wind velocities to be used in determining light fixture pole capability.
Note: If during the pole warranty period of one year, the product proves defective in material or workmanship, the company shall correct, at its option, by repairing or replacing at no charge to the purchaser, if the purchaser promptly notifies the company. This warranty specifically excludes fatigue failure or similar phenomena resulting from induced vibration harmonic oscillation or resonance associated with the movement of air currents around the product.
Pole Selection Procedure:
Step 1. Select the light fixture and decide how many will be mounted per pole. Determine the effective projected area, EPA (ft sq), which is given on the dimensional information table.
Step 2. Determine the appropriate mounting method for the fixture. Options include arm, bracket or wall mounting.
Step 3. Add together the EPAs (ft sq) of the light fixture and arm/bracket. Multiply by number of fixtures to be mounted on one pole.
Step 4. Consult the wind map below to determine the basic wind velocity for your area.
Step 5. Select the material (steel or aluminum) and shape (square or round) of the pole (refer to Ordering Tree).
a. Find the desired nominal mounting height in the second column.
b. Verify that the fixture weight does not exceed the maximum weight listed for the desired pole.
c. Compare your total EPA (ft sq) loading with the maximum EPA (ft sq) value found in the wind speed column for your area. Check that the equipment you are using will not exceed this value.
d. If both the weight and EPA (ft sq) valued does not exceed the value for which the pole is rated, you have selected the correct pole. If, however, either one of those numbers exceeds the maximum rated values, compare the EPA (ft sq) and fixture weight loads to the next larger pole of the same mounting height.
Note: “Call Before Number” and complete pole description MUST be included before order can be processed. Bolt templates will be shipped with anchor bolts. To pre-ship templates, place an order for the appropriate template number.
Caution: This pole selection process is a guideline only. Acuity Brands assumes no responsibility for selection and recommends consultation with qualified individuals for verification of light fixture or pole assembly selection.
