This electrical wiring question came from: Neil, from Cancun, Mexico.
Dave The Electrician’s Reply:
Thanks for your electrical wiring question Neil.
Careful Planning for Electrical Service Changes
Please be advised that this is a question from Mexico dealing with an electrical service that is not typical for Residential or Home Electrical Services in the U.S.A.
Skill Level: Advanced – Licensed Electrical Contractor, Not Recommended for Homeowners.
Tools Required: Electricians pouch of hand tools and the various power tools necessary for the specific service upgrade.
Estimated Time: Depends on the type of panel and available access to the project area.
Precaution: This is an extensive project that should be performed by a Licensed Electrical Contractor.
Notice: Making changes to the Electrical Service Panel should be done according to local and national electrical codes with a permit and be inspected.
- Neil, you have not mentioned the neutral conductor for the electrical services, and if the neutral has not been supplied to the office panel then it too will need to be connected along with the other phase conductors.
- From the information that has been provided with this question it would be good to consider the following:
- Be sure that the primary service conductors of the original office electrical service are disconnected to avoid back feeding any other existing wiring.
- All circuit wire conductor types and sizes must be properly protected by an over current device or circuit breaker.
- All electrical work including service panel modifications should be installed with a permit and inspected.
