I live in Illinios and code requires that i use conduit. Is it wrong to pull 12/3 cable (romex) thru it or does it have to separate conductors? also which would you use if you had to pull separate conductors solid or stranded? The runs are generally 12-16' long to the sub-panel. thx

Hi I want to limit/stop access to my outdoor outlet - I live in a condo and the contractors use anybody's outlet they please - my electric bill is high enough and once in a while is one thing but these guys come to my power for their power tools every time they're here. I looked at the circuit breaker board and there's just one switch for lights - the rest are for each appliance. I don't want to have to turn off all the "lights" every day by shutting off the circuit breaker so would like to know if there's an easy way to limit access - at least so I would give a contractor access at my discretion. Can I: get a hasp that will cover the two outlets (there's flip covers on each) so I can lock the access with a padlock Or, can I easily myself shut off the power to the two outlets by undoing wiring Or, do I need to call an electrician or build a cover myself? I called a couple of local electrical supply houses and asked about locking covers and one guy said that he has's seen them offered by his supplier for several years. Thanks for your help!
