This is a guide for the proper selection of filament lamps for use in roadway lighting equipment covered by the following American National Standards: C136.4 through C136.7 and C136.11.
This standard is intended to provide a simple, uniform method for identifying the type and wattage rating of a high-intensity-discharge or low-pressure-sodium lamp installed in a luminaire.
Surge-protective devices designed for application on the low-voltage ac supply mains (1000 V rms and less, frequency between 48 Hz and 62 Hz) are covered.
A two-terminal avalanche junction surge suppressor for surge-protective application on systems with dc to 420-Hz frequency and voltages equal to or less than 1000 V rms or 1200 V dc…
