I just replaced a 3 way lamp socket and used a regular granny knot on the cord. Should I redo it with an underwriter knot? Not sure how important it is. This lamp has two restraint bushings. One where cord enters base and another where cord enters socket. That cord ain’t going anywhere. Maybe I do not need any knot? Thanks.

If the bushng grips and puts a kink in the cable to prevent the cable from slipping and pulling out if yanked, then no underwirters knot is required.

An underwriters knot is less likely to be pulled through a hole of a given size compared with a granny knot or an overhand knot.
