Traffic Signal Cabinet Base - Cross Reference Guide

Using This Selection Guide Follow the steps outlined in this guide to select the appropriate traffic signal cabinet base for your application. For more information or for answers to any questions you might have, call your local Hubbell representative. Detailed product drawings are included in this section and also can be accessed from the website.

1. Determine Type of Cabinet Hubbell offers a variety of traffic signal cabinet bases that work with most NEMA and 170E cabinets manufactured today. The footprint of the cabinet will determine which base to install. Please see the Traffic Signal Cabinet Base Cross Reference Guide on pages 102 - 109 to choose the proper base for your application. If your cabinet is not listed, feel free to contact your local Hubbell representative. Throat sizes and insert locations can be tailored to meet your requirements. 2. Determine Work Pad Requirements Hubbell offers work pads to accompany all of the traffic signal cabinet bases. If the cabinet is to be installed on a surface other than a sidewalk, a work pad may be necessary to provide stable, dry footing. An alternative option to using a flat work pad in front of the traffic signal cabinet base is to use an enclosure instead. An enclosure serves as a splice box and the work pad also provides a skid resistant walking surface. Hubbell offers a wide variety of enclosure sizes and depths to choose

from. Your local Hubbell representative is available to assist you in selecting the appropriate enclosure and options to suit your application.

Many Departments of Transportation choose Hubbell traffic signal cabinet bases when they have projects requiring new and retrofit installations of traffic control cabinets. Hubbell traffic signal cabinet bases are less expensive than concrete to install, can be quickly installed by employees, can be relocated and can reduce potential injury and/or liability if struck by a vehicle. In the application pictured, the DOT had previously poured concrete in place for each traffic signal foundation. The installation process using concrete could take up to a week or more depending on weather and involved having to schedule around other work crews. The cost of the Quazite base was approximately half the cost of the cast-in-place concrete method and installation time was reduced to one-half day.
