I have a customer who ran General Cat6 wire in his building (he bought wire from big box store). He asked me to terminate the ends and set his network up. I installed the Cat 6 Jacks and everything was going well. But on the other end I tried to install the plugs I got for Cat 6 and the wire seems to large for the "sled" that is part of the cat 6 plug. I cannot even get the wire into this thing before putting the sled in the plug. I tried an RJ45 and it is just about impossible to get all 8 Cat 6 wires into the plug. Any idea what I may be doing incorrectly? Could the Cat 6 wire be too large?
