Double Taps On Breakers
This weeks blog is about “double taps”. During the inspection process we inspect all electrical panels. There are several reasons why this process is done. And in this blog I am going to share about electrical inspections and electrical safety. So lets begin.
During the inspection process part of the electrical inspection is to inspect the panel box and sub-panel boxes. In Florida, we have with new construction a main breaker at the meter then that feeds to the panel box that maybe in the garage or bedroom. This is nice when a technician has to work on the panel. So while inspecting we check both. A lot of times the main disconnect may have a breaker for outside lighting or the pool equipment. With some homes, they almost use it as the main panel to feed the shed and/or other equipment. However, we also have the double tap as well.
Some non-experienced workers will run a feed for an exterior circuit to the main electric feeds. Or if there is a small amp circuit for an additional receptacle they will tap off a 20 amp breaker because the panel box is full. Neither are appropriate and are not safe. The entire purpose of the breakers are in-case the amperage is to high the breaker will trip. Imagine operating heavy mechanical equipment that require 30 amps in your bedroom from the circuit that is only 15 amps. The circuit will trip every time and then the eventually cause damage to the main. As so this is true double tapping any other breaker or main. If the panel is full then either a sub-panel is needed or a complete upgrade. Yes it can be costly but it is safer. Now I have seen also where people will install an exterior receptacle and tap it to an appliance breaker. This is not good either. The starting amps for an appliance is going to be within 10% of the breaker allowed amperage. So if there is a tap to the heat-pump for that circuit and the unit comes on as you start up a weed wacker again you could trip the breaker or cause more damage then known.
So whats the solution. When adding additional circuits there is a proper process. Yes you can look on the internet but if you do not know electrical math to gain the resistance and amperage of a said circuit you could really do damage to the homes wiring. When we find these deficiencies we immediately tag the circuit. If the circuit is not energizing any food appliances we suggest to the home owner or agent that we would like to shut off the breaker as it is unsafe. This deficiency is marked in the report and we usually have to do a return visit to inspect the deficiency being corrected. By no means is this a deal killer for a transaction but it needs to be attended too.
