A:<\/strong> Yes, for most power or mechanical applications. Crimping creates a gas-tight joint that doesn\u2019t weaken over time.<\/p>\n
A:<\/strong> Not recommended. Tape alone isn\u2019t secure or up to electrical code.<\/p>\n
A:<\/strong> Yes, if rated for your wire gauge and amperage. WAGO and similar types are UL-listed.<\/p>\n
