I cannot believe I’m encouraging this. If you ask for an extinguisher from fire, they will more than likely want to come take a look at your house to check for safety hazards. If you aren’t afraid of electrics, you should ask @Rye, @Jared for advice on your electrics. I’m not saying they can absolutely help you, but I know they speak electric, as does @Mrb53004. It’s better to figure it out that way than the backwards way when it comes to electricity. Not sure where they would want such a thing posted. I’m a fire medic’s daughter, so I know just enough to know what’s safe and not, but I’m not comfortable with giving directions on outlets, plugs, timers, etc. I’ll send you one though.
