Yes and considering you have to ask I would suggest that you get an electrician to do it. In any case the power should be turned of prior to attempting to do anything. House power can be deadly. Turn off all of the circuit breakers in your home/apartment prior to doing anything to it, wear gloves when you yank it, and make sure to use plastic- or rubber-insulated pliers to pull it.
The symbol for "prior to" is "<".
Prior to entering an electrostatic precipitator (ESP), ensure that the power supply is switched off and the system is properly grounded to prevent electrical shock. Wear appropriate personal protective equipment such as gloves, safety glasses, and a hard hat to prevent injuries. It is also recommended to follow lockout/tagout procedures to ensure the system cannot be accidentally turned on while maintenance is being performed.
Live working is generally permitted only in exceptional circumstances when it is necessary for the operation, maintenance, or repair of electrical equipment and when alternative methods are not feasible. Specific safety protocols must be followed, including the use of appropriate personal protective equipment (PPE) and the implementation of safety measures to minimize risks. Additionally, live working must be conducted by trained and competent personnel, and typically requires prior risk assessments and safety planning to ensure worker safety. Regulations may vary by jurisdiction, so it's critical to adhere to local laws and guidelines.
its posable that 100amps direct burial cable (copper at your best) in my sugestion should be a minium size of 2/0 and ground size of #2 this is stepped up for voltage drop concerns. check your authority first prior to any work ,
Depends on what the consequences of a bad grounding is. If it is life threatening, I would check it prior to operating the equipment. If it is mission critical, I would check it weekly. If it is an annoyance, I would check it when symptoms developed.

You should understand how the equipment works. You should also know any safety informtion you should know prior to operating.
General notes
FAM/CEMO EC/EAO must obtain FAM/CEMO approval prior to transferring equipment.
Did not check for local hazards prior to launching
firstly check calibration dates, PAT testing and give the tool a visual check to ensure it is in good physical state to use. if it has a a test procedure, this should be followed accordingly. (^rough answer - jtl might not accept it lol)
To have your gear (or equipment) ready prior to deployment.
The procedure for ensuring that all tools and equipment are available prior to undertaking an activity is:assess needsgather needed tool and equipmenttest to confirm they work
All documentation should be stored in the correct place, this makes it easier to be found when needed and less likely to be lost. Prior to starting the activity you should check the documentation is available to you, if it is not then it should be soused from a manager or supervisor. It is important to check that the documentation is up to date as old documentation can cause mistakes and scrap material. So dates on documentation should always be checked.A good filing and logging system should ensure everything is available in its own place for any specific task, ie: manufacturers data sheets, PPE requirement documents, Job methods, Permits to work.This should ensure no emission of relating documentation.A visual assessment of the job, materials/parts and tools expected to be used supported by a check list should be carried out. This will make you aware of the tools and equipment that will be used and you can check that they are available.
