Home inspection
The home has three metered electrical service. There are many problems with this service. It is over loaded and installed in an unprofessional manner. All of which would be corrected with an electrical service upgrade. All the boxes here can be combined into one meter and panel. The intended use of the home will be as a single family. Setting up the service to match the usage will correct these problems.
There were many points in the basement where junctions were not installed correctly. These wires should be re-junctioned and boxes covered. The wiring is a hazardous to be left this way. The corrections needed to repair this wiring are minor
There was a sub-panel on the second floor that is over loaded and rusting. This panel should be replaced with a newer larger sub-panel. Electrical panels should be replaced every 30 to 40 years. This panel is about that age. The wiring in the panel is modern wire with grounds. It looks to be in good condition.
All the outlets that we were able to test were correct. There was on outlet on the first floor by the bathroom that was missing a ground wire. There was also this box on the second floor that we were not able to access. Everything in the house was working at the time of testing. The only issue is that there were long areas of walls that had no electrical outlet.

How to install recessed lights in a living room
Living room lighting with recessed lights.
Wiring recessed lights
Here we are cutting the hole that are needed to add the lighting can into the plaster ceiling. There are hole made at every floor joist in order to run the wires across the living room ceiling. We try to keep the hole small so that they patch easily.

PECO's power line going bad
No Power in the house because of Service Cable.
This is a video of a house that lost power. The cable outside that attached to the PECO power lines has rotted away. The outside cable looks to be about 40 to 50 years old. The outer jacket of the cable is is no longer intact. The sun and weather has washed away the jacket exposing the the wires on the inside of the cable. There are three parts to this cable. A Black wire, A Red wire and a bunch of Aluminum that wrap around the the cable.
The RED&Black wires delivers 120volts to ground or 240 volt between each other. The Aluminum wires warping the cable is the ground. After the jacket of the cable weathered away the Aluminum ground became exposed to the elements. The ground wire is the return path for your power. When that dissolved in the weather the cable started to smoke and power was lost to this house.
On the inside we can see the fuse panel that is attached to the cable that failed. This electrical system should have been updated years ago. Letting your electrical equipment get this old is like driving a car on bald tires. Your car will run fine until the tire pops. Most of the time you will get lucky and have no real problem just a flat. Occasionally you could find yourself stranded. On rare occasion this lack of maintenance end in a tragic accident.
This client was just left stranded. They did not plan on this unexpected expense when they lost their power. They were very inconvenience and has had no power for several day. I think that they were lucky. This problem could have cause a house fire. They could of ended up with no electricity and no house.

Trouble shooting an AFCI outlet circuit
The power stopped work on this bedroom circuit. This is how I trouble shot the circuit.
The first step was to open up a wall box and take a look at the wiring. This outlet had a loose ground. This made me believe that the electrician who wired these outlet was only a helper and not highly skilled. Lose ground connections are too common and can cause problem with your electronics.
To find the circuit that has lost power I tied the neutral and ground wire together. This should never be left this way. This is only done as a test. Tying this neutral and the ground together will create a continuity in the circuit back at the panel. In a normal circuit the ground and neutral would not touch.
Back at the panel, I know that the circuit is one of two AFCI circuits because the loss of power occurred in a bedroom. Starting in 1999 Arc Fault Circuit Interrupter (AFCI) breaker have been required for all bedroom circuits. AFCI are designed to turn circuits off by detecting non-intended arcs. Arc faults in a home are one of the leading causes for household fires.
To test which circuit is connected to the outlets that are not working. All I needed to is see if there was continuity between the neutral and the ground. The circuit with continuity is the circuit that I put the ground and neutral together.
Now, that I know what circuit breaker is controlling the outlets that stopped working. I note everything in the house that is working. Then I turn off the circuit breaker that is controlling the bad circuit. With the circuit breaker off I then look to see if any of the outlets that were “on” turned “off “ when the breaker is off.
This time one did. Opening the outlet I found a bad connection in the back of the outlet. Power was getting too this outlet but not leaving it.
The stab-locks on the back of outlets fail too often for my liking. They are used in new construction because they are the fastest way to install outlet. They can also be installed by unskilled helpers. They are not the best way to install outlet. I do not let my technicians use the stab lock. We install outlet by using the screws on the side and making pig tail connections. These types of connections are much better. Connecting your outlets this way will improve the overall condition of you power.
The best way to wire an Outlet
This is the outlet with the pigtail connection. The wires are connected to the outlet on the screw terminals. The wires that go "IN" then "OUT" are connected at the pigtail. This outlet can be change without affecting the power anywhere else in the house.
If the first contractor wire the outlets this way they would have never failed

A dryer plug makes a better mouse trap
Electrocuted mouse
This is sweet revenge for an electrician. Mice normally are eating your wires. It is nice to see the homes wiring fighting back.

What is behind the wall is what counts!!!
Knob and Tube wiring is quickly moving from outdated to dangerous!!!
Above is a picture of that same switch and outlet pictured from behind. Here you can see the cloth and tar covered wires that feed the newer outlet and switch. The wiring has done a good job for many years but time has clearly aged this installation. Knob and tube wiring has been outdated now for over 50 year. Many insurance companies are starting to move it over in to the dangerous category. Either raising premiums or just not covering it.
The picture above show details of different conditions knob and tube wiring can be in when the walls are opened. The most alarming thing we find is how different contractors have added to or changes how the wires were intended to be used. The electrical systems that were installed in the first half of this century were never intended to power the type of wonderful thing in the modern home.

There are No ghost in you wires
Only gremlins!!
Happy halloween
I just left a house today with mysterious electrical problems. The house had rooms that stopped working and lights that flickered. This is a common problem that people have and too often it gets ignored. If some of your electric stops working it needs to be fixed! It is a dangerous idea to just blame that non-working light or outlet on ghosts. The real reason most electric stops work is due to a bad connection. Bad connections can start a fire that will destroy your home.

Knob and Tube wiring caught on fire.
Dangerous of old wiring
This is a close up picture of what could have been a real tragedy. There was a 1930's knob and tube outlet cut into this base board. If you look closely you can see the square coroners of where the outlet use to be. The wiring to this outlet failed. The outlet started to short out but not enough to trip the circuit breaker. This started a small smoldering fire.
This fire was starting to work its way up the wall space when the owner found it. Luckily for her she had to come across the fire by accident. By the time all the children were gathered and brought outside there was smoke coming out of the roof of this home. The fire department was able to stop the fire before it spread anywhere else.
Still the water damage from the fire started by one outlet on a closet wall was extensive. After the fire department left three floors of this house had major water damage from the fire hoses.
KNOB AND TUBE WIRING SHOULD TO BE REPLACE WHEN EVER IT CAN.
Peco's Responsibility?
Who's problem is this??
Many home owners are not sure where the electric company stops being responsible for the utility wires. In this picture you can see both Peco's power lines and the power line from this home meeting. Peco's line is the line that is running along the top of the house. The home owner's line is the one running vertical up the side of the home. PECO's responsibly stops at the point where the two wires meet.
The home owner's like has become detached from the home. This is the responsibly of the homeowner to have repaired. Meter reader reports report unsafe wiring to PECO. Sometimes PECO will cut line like this of the power grid without warning because they are dangerous.
