It depends on the work. If it's something that has to be up-to-code, it must be done properly or your house can be condemned by the state.
yes
No, anyone is allowed to bid for new jobs. An electrician needs a journeyman's license to legally control and supervise one electrical construction project under supervision of a master electrician who can obtain the electrical building permit and who is allowed to supervise and control as many projects his capability will permit.
To upgrade to a 200 amp electrical panel in a residential property, you will typically need to have enough physical space for the new panel, obtain a permit from your local building department, hire a licensed electrician to do the installation, and ensure that your current electrical system can support the increased capacity.
Yes. Should be done by a qualified electrician with the proper permit.
This is not a DIY project. When lives are involved the best bet is to get a qualified electrician to permit and do the job.
Depending on your state, most general contractors have to purchase a temporary electrical work permit to perform any electrical work in your home or business. Alternately, they can hire an electrician as a sub-contractor. Thanks.
The necessary requirements for installing a 100 amp service panel in a residential property include obtaining a permit from the local building department, ensuring the panel meets the National Electrical Code standards, having the panel installed by a licensed electrician, and ensuring proper grounding and bonding of the panel.
The necessary requirements for installing a 400 amp service panel in a residential property include obtaining a permit from the local building department, hiring a licensed electrician to do the installation, ensuring the electrical system can handle the increased capacity, and complying with all relevant building codes and regulations.
No the service wires need to be upgrade to 3/0 copper or 250 mcm aluminum. This will require a power company to disconnect so you can upgrade the service. These wires are always hot unless the power company disconnects from their source. Do it right pull a permit and upgradeAdditional information:Some meter base boxes include a shutoff/breaker. If you are only looking for additional space inside the breaker panel, and do not upgrade to a higher amperage breaker inside the meter base, you actually CAN use the same wire, provided that it is long enough to reach into the new breaker panel. The breaker of the meter base protects from the over-current condition.If you have the shutoff in the meter base, you will obviously be able to disconnect service while you perform the necessary changes. While you are working on the service, lock-out the meter base access to prevent anyone from turning the power back on.It is still recommended that you pull a permit and work with a qualified electrician.
You will have to check you local codes. Sometimes if an outside plumber or electrician is involved they will have to pull a permit.
Generally, no. Most states regulate the "practice" of doing electrical work for others, and an employee would almost certainly be practicing the trade of electrician, and would thus need a license if not a building permit (which may or may not require an official inspection, depending upon what the work is, and whether the jurisdiction inspects such work). On the other hand, some states permit a homeowner to do minor plumbing or electrical work without a license, although a permit may be required. Finally, some jurisdictions don't care who does the work until someone gets killed because of a mistake, and the answer to your question would be "yes, but they had better clear it with their insurance company."
