The table at the top details the characteristics of Regular Lamps with candlepower ratings ranging from 10 C.P. to 100 C.P., listing corresponding voltage, ohms, and amps. Below, there are separate sections for 3 Ampere and 4 Ampere Municipal Lamps, with similar calculations. The blueprint features precisely hand-drawn tables with ornate script headers, characteristic of Edison-era engineering documents.
This blueprint contains detailed tabular data for various types of lamps, including Regular Lamps, 3 Ampere Municipal Lamps, and 4 Ampere Municipal Lamps. The data includes calculations for different candlepower (C.P.) ratings, such as 10 C.P., 16 C.P., 32 C.P., and 50 C.P., providing values for voltage, current (amps), resistance (ohms), and total channel calculations. This document is likely part of Edison-era lighting system documentation, possibly from the late 19th to early 20th century, used for municipal and commercial lighting systems.
