				At the risk of sounding like a complete idiot....    I have searched the archives, Bob's AC, and AC43.13 and found nothing that addresses the question "can I (for example) put two 20AWG wires in a 18AWG crimp-on terminal"?  Does this defy best practices?  It would be electrically sound, mechanically sound, and I think gas-tight.  Is it better to lap solder a Y connection with shrink tube and then have a single wire going in the crimped terminal?
 
 Along the same lines, how about a solder connection on a switch terminal that needs two wires attached to it?  I think the answer to that one is the lap soldered Y.
 
 The answer is probably in one of the cited places but I can't seem to come up with the right search words.

    Not at all.

    How big a terminal and what size wires. Generally
    speaking, a solder-terminal on a switch is robust
    enough to handle wires rated at a level similar to
    the switch. For example:

  [img]cid:7.1.0.9.0.20110622191232.01ff9fb8(at)aeroelectric.com.0[/img] 
 
    This 5A switch handles 22AWG wires nicely. But I
    probably wouldn't pile more than 2 such wires
    onto one terminal.

    Switches like this are wired with ring terminals.
    I've seen a couple of terminals stacked onto one
    screw with perhaps 4-5 total wires. It's pretty
    much a judgement call. If in doubt, don't add more
    wires.

				General question on crimping. Is it better to twist the wires together, 
 in the case of multiple wires, or to twist the strands of a single wire 
 or is it better to have them straight and parallel to the sleeve?
 
 Thanks.

    Straight and parallel.
