Working on original wiring issues that was installed by some licensed electricians is not for the faint of heart or non experience or knowledgeable troubleshooters. As it takes years of hands on skills to become proficient in the abilities that it takes to get projects completed A to Z with with quality craftsmanship.
This phase of past and current client troubleshooting issue stems from a outbuilding that had a attached indoor greenhouse. A #14-2 w ground 15 amp 120 volt NMB romex cable was stabbed thru the wall for greenhouse feed terminating inside a single gang plastic nail on box that usually is put inside walls for outlets ect but in this case it was screwed to the outside outbuilding wall for greenhouse power? Reusing the existing power tap but terminating it inside a single gang weatherproof box now called my splice box power feed. After removing all the other old NMB wiring, splitters, extension cords and cowboy electrical new PVC conduit and weatherproof boxes and covers were used for single pole switch for 2 over head LED 4' lights and 4 outlets load side of GFCI lineside. Turning power back on bang goes the breaker? Troubleshooting revealed that over 20 openings (lights and plugs) were being controlled by this 15 amp 120 volt circurit breaker. Along with a old dinosaur of a refrigerator load and now the Greenhouse load.
Ok the fix as it's always is that it's in the numbers is to take the greenhouse and add it onto it's own circuit breaker as well as add another circuit breaker for the old dynasoar refrigerator. By taking these 2 loads off of the overloaded over 20 openings original circuit breaker still does not solve that issue but it does free up 7 spaces now lowering the 20 to 13 openings on a 15 amp 120 volt circuit breaker. The fix than is to add yet another circurit breaker and split the 13 openings between the 2 circuit breakers. And splitting circuits up in original wiring that is behind closed walls and ceilings that is stapled in place is not fun in the least.
By openings I mean a outlet is a opening a light fixture is a opening and by code you are allowed X number of openings for the amperage of the circurit breaker that it is designed to control the branch circuit wiring and device openings being operated. It seems as some electricians do not know how to count as I see overloaded openings in residential usage on a regular basis. Usually problems do not occur until more and more things are being plugged in and being operated than it is a call to a quality craftsman to figure out what in the dickens is going on?
