a few months ago i installed a dimmer light switch in my garage for a halogen lamp. but after i installed the dimmer switch i had a left over wire. The lamp and dimmer switch was working just fine even though i had an extra wire left over. So i grounded it with a wire connector ( it may be a crappy ground because i didnt ground it good enough ). Since then i've notice my mother complaing about higher electrical bills. I was wondering if that left over wire could be causing a never ending electrical current causing it to be on 24.7. i have no experience with electronics or the way electricity works. I installed the dimmer light switch with the help of instructions online and also the instructions that came with the dimmer light switch. But on both instructions they showed that there were 3 wires. But in actuallity when i opened the outlet there were 4 connected to the stock light switch. i was really confused and just connected 3 wires and to my surprise the dimmer worked. Anyways i need some advice to see if that extra wire is causing an increase on my electric bill. Thank you.

 

Don't know what the left over wire was but you probably should not have grounded it. You should just put a wire nut on it to cap it. Don't connect it to anything.

 

is a wire nutt one of those orange cones that u put the wire in then twist? cause that's what i used.

 

No, that extra wire is not affecting your electric bill.
