6.The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.

(See Figure C.)

7.When using more than one extension cord to make up the total length, make sure each cord contains at least the minimum wire size required.

(See Figure C.)

8.If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum cord size.

(See Figure C.)
