[D8828ACO], Letter from Schuyler Skaats Wheeler to Thomas Alva Edison, July 27th, 1888

Editor's Notes

"Can you give me data on the carrying capacities of copper wires? ### How much current can wires that are covered up (in moulding, tubes, or cables) carry without becoming too hot for safety and how much current can wires in the open air carry without becoming hot? If you can give me this in amperes per circular mill, I can apply it to all sizes of copper wire. ### I am getting up a complete table for wiremen and want to print the sizes that get warm covered up, in small type, and those that get hot even when exposed, in red letters. ### If you can furnish this I will be obliged." Yours truly, SS Wheeler [Marginalia: "Refer him to J.H. Vail EE&Co 16 Broad. V has all the tables. E"
