Re: Wire preference - stranded or solid

Let's start out with the first post. Either stranded wire or solid wire can be used on the robot. Either can be bent at 90 degrees, solid will hold that bend better than stranded. The Wago terminations are better suited for stranded, untinned wire insertion of one wire only. As the wire is inserted and the terminal is allowed to compress it, more surface area is created between the wire and the terminal giving a lower contact resistance. Tinned, stranded wire often reduces contact surface area to a fraction of either wire terminations raising the contact resistance and therefore heating the contact. Although the PD can accept solid wire termination, stranded is better in my opinion. Solid wire on moving and vibrating objects is asking for wire failure due to flexing of a single conductor. Stranded wire handles vibration with far less metal fatigue.
