The original Wire Nut page incorrectly included a Quick Splice Connector specification image. It is replaced with the corresponding SP wire-nut dimension illustration while preserving the image count. The original descriptive text says metal spring, whereas the catalogue image says copper tube; confirm actual internal construction. Model SP6 is retained exactly as supplied; no SP5 is invented.
Selection Guide
Provide conductor count, sizes, material and stranded or solid construction. Confirm the model’s approved wire combination, stripping length and connection method before installation. The original wire-combination expressions below are catalogue references, not a universal minimum-to-maximum range.
Applications
Potential uses include equipment, lighting and junction-box connections where the selected wire nut and conductor combination meet the installation requirements. This standard wire nut page does not establish a waterproof or direct-burial rating.
Ordering Information
Send the complete SP model reference, conductor sizes and count, application, quantity and required documents. Include sample, inspection and packaging preferences.
