How to use the Mueller clip and insulator chart

Click or tap to expand
Find a clip or work backward from an insulator

Enter a clip number to view its specifications and listed insulator. To find clips for an insulator, search its reference or choose it in the insulator filter. For example, BU-60 lists BU-62*, while BU-30 lists BU-32*. The insulator button on each matching entry applies the same filter.

Compare the connection details

Use the amp and jaw-opening filters to narrow the chart, then compare wire attachment, wire AWG and length. The attachment filter finds clips that list the selected method, including entries with more than one method. The AWG filter matches the exact chart entry, including ranges and “Up to” designations.

Understand insulator statuses

Most entries have the insulator part number linked. Other entries use Insulated, Insulated Barrel, Included, None, or NA.
