I don't know if this applies to a breaker panel, but instructions for Hubbell brand plugs and sockets say not to tin the wires. The advice from dougrainer is good.
Edit: Found the following on Hubbell's web site:
"Wire tinning, for the purpose of containing loose wire strands, is not a recommended practice for use with clamp/ screw terminations in wiring devices. The thermal properties of solder tend to allow for the redistribution of wire strands, particularly due the heating and cooling cycles common to wiring devices. This occurrence is commonly referred to as "cold-flow." In long-term usage, cold-flow could result in a runaway thermal condition progressing to excessive heat, arcing and/or fire."
