! t$ [8 u. i% G3 w# i6 `# XIn my memory , in Canadian Electrical Code, there are tow tables(表格) regarding the #14 wire. One table tells you: when wires go together, like in a EMT, if the number of wire is >3, the one of #14 wire can feed 15 A currency. Another table tells you: if the number of wire is =< 3, the one of #14 wire can hold 20 A currency. In order to make sure, you can check the tables in the Code book. Are you an apprentice ? |
