Have a 1000W and a 400W going on at the same time in two rooms. They work fine but when I use the microwave the lights go out. What can I do to fix this?
There are three main options. First, you can upgrade the breaker to a higher amperage one and run new, lower gauge cables from it to all outlets it currently connects to. Second, you can install a totally new breaker specifically to run your lamps off of. Purchase the correct gauge cables to go with it and run them to the outlets the lamps use. Third and least costly, you can connect the cable powering the microwave's outlet to a different breaker. Some calculating will need to be done to find out if the alternate breaker has enough available amperage for the microwave and anything else you may plug into its outlets in the future. *Always turn off the main breaker before performing any work at the breaker box. Failure to do so can cause electric shock, injury or even death. *Always use cables with a gauge capable of supporting the breaker's amperage. Failure to do so can easily cause a fire, likely in the future when you won't be expecting it. *Always turn off the breaker(s) governing the circuits you're working on/near when performing any work on household wiring. Test the circuits to be certain they're cold before any work is done. Failure to do so can cause electric shock, injury or even death. *Make sure all connections are properly done and secure. Failure to do so can easily cause a fire, likely in the future when you won't be expecting it. *Do not perform any work on household electrical circuits if you do not know how or are unsure of any procedure.
