Research & Writing Assignment:
I read an article about ‘Electrical Safety’ and thought about it.
Most of the homes over 30 years old in my country are missing the main ground.
So such homes are missing the grounding of the outlet or receptacle.
It means that when a person is exposed to an electric shock, it can cause fatal damage to the human body.
I hope that our government will be more regulated.

Essay based on article-Electrical Service Panels
by Nick Gromicko.
Electrical panels are enclosures that contain circuit breakers, which are protection devices which cease the electrical current if it exceeds the safe working level for a circuit in an electrical system.
Advise your client that they should never remove an electrical panel cover themselves, as lethal electrical explosions have been the result of opening electrical panels.
Before touching the electrical panel, proper PPE should be wore and then an inspector should test the panel for being electrically charged, if that is the case the panel should be deemed a defect and a licensed electrician should evaluate without haste.

Most of the homes over 30 years old in my country are missing the main ground.
My home is one of those homes.
The panel of the photograph is made of wood and the front cover is missing. Moreover, the cover of the power relay is also missing, which is very dangerous.
These are the items to be corrected.

during inspection of this 200 amp service panel located in the north wall of the garage i observed a loose service conductor at the termination point at the neutral lug and 2 unidentified white wires and 2 missing screws in the dead front cover defective recommend further evaluation by a qualified electric contractor
Research & Writing Assignment:
i have chosen to speak to the safety concerns dealing with dead front removal it is very important to check the cover before handling the cover and it is very important to use the cover as a shield while removing in case a breaker or loose conductor falls out
Those breakers are listed for two conductors.

Electrical Inspection
Siemens= rainproof combination metering
Rating 200amp max 120/240 volts ac 1 phase 3 wire.
suitable only for use as service equipment.
Picture of service equipment has a (minor) defect missing labeling of a 30amp fuse .I Traced wiring to the bottom newer unpainted electrical conduit from service equipment to a mini-split a/c unit max fuse size 35a min. circuit 25a so 30a is ok.
Visual inspection of equipment grounding ok.
Note there are two a/c systems one is a central a/c unit with 35a breaker the 30amp is for the mini split.

Electrical service panels are connection between wires coming from the tall electrical pole in your yard or street area, some even come from a huge steel transformer box out with wires safely hidden underground that makes its way to your service panel.
Service panels are call many names : fuse box, fuse panel, circuit breakers panel.
In the 1960s the circuit breaker panel came on the scene and has remained the standard every since.

Article Surge Protectors.
In my area (Florida = lighting) many Main Disconnect Panels have an Utility installed surge protector either in or adjacent to it.
I learned about good-better-best ratings and capacities from this article.
Clamping voltage - Three levels of protection: 330V, 400V and 500V. Lower clamping voltages offer better protection.
Energy absorption - Higher numbers, such as 600 joules or more, indicate better protection.
Response time - High-quality suppressors will activate in less than one nanosecond.
Inspection & Writing Assignment:
During an inspection of the incoming service, the main service disconnect after the meter, several issues were found. 1st there is not a bonding screw in the panel (required by NEC), 2nd the main breaker for the panel is a 200Amp with a 100Amp and a 70Amp breakers feeding additional out building subpanels. Also after completing the interior part of the home inspection, there where (2) 200Amp panels inside the home. Noted that the incoming panel must be checked out by a licensed electrician to correct issues and verify panel. 200Amp main with combined loads may be above the 200Amp rating.

Electrical Panel inspections. 1st make sure the panel cover and/ or box casing is not energized. Check for the proper type of screws, wrong screws securing the cover to the box could cut into the insulation of a wire to close to the attachment screws. there is a lot more to do during an electrical panel inspection, but these should be a few of the items on the 1st part of the inspection to check and notice.

The image shows a 200 Amp. Siemens interior load center. At the time of the inspection, all circut breakers, GFICs and AFCI breakers appeared in operable condition. Panel is located in garage of residence. There were no breakers in the off position at the time of the inspection. The service is a underground lateral type. Cables that feed the panel are non-metalic sheathed cable. There is some minor damage at the top of the panel cover to drywall and recommend repair. Confirmation of 200 amp service from three sources, main circuit breaker, panel cover and electric meter on exterior wall outside of panel. There appears no major safety of functional concerns at time of inspection.
