I'm installing undercabinet halogen puck lights (a plug in kit). I'm going to direct wire to the existing wire that ran two seperate fluorescents, turned on by a wall switch. Beside this switch is a plug. This is a two part question. 1. The halogen kit has a transformer and is intended for a plug in installation. Can I run the existing house wires into a box and join the halogen plug in wire to them (white ribbed wire to white existing wire, black to other wire) 2. I believe the existing wires are 220, typical in a kitchen. (I found out the hard way, touching a live white wire, when I thought the power was off at the wall plug, the switch must be independent) The old fluorescents are wired for 110. A black, white and ground. If the house white is hot does this present a problem? thanks....John

We have recently purchased a new house and are not familiar with the wiring. We have been tripping a 20A circuit breaker when the switch is turned on to our outside lights. We have unwired the switches and here is what is in the (2) switch box. (2) Black / white / ground wires going into the box (probably chained into the box from somewhere else. (1) Black / White / ground wire going to a ceiling light ( which is one separate switch) and one Black / White / Red / Ground wire which went to the other switch for the outside light. The wires are connected in the basement into a connection box. In that box, the whites were all connected together, the blacks were connected together and the one red wire was connected to the single wire leading to the outside light. What is the proper wiring in the switch box for the two switches and why was the red wire from the outside light switch connected to the black wire leading to the physical outdoor lighe??
