    I returned from out-of-town and the 4-bulb light fixture in my bathroom wasn't working at all. I've checked and replaced the bulbs (all ok), and used a current detector to confirm (at least some) power to the switch, power to each individual bulb fixture, and that power to each fixture is...

    Hello, I recently purchased some utilitech undercabinet low voltage LED puck lights from lowes, slim seek polished metal ones.

    I am new to this forum so bare with me. There are several posts on converting a 3 prong outlet to a 4 prong outlet to meet the more up to date codes. Regrettably, my house id from the 80's and the builders were cheap you-know-whats and the 10/3 wire they ran to my dryer did not have a bare...
