You need to cautiously choose an electrical contractor when you are planning a brand new installation. The electrician you decide on must suit your schedule, spending budget, and standard of work expected. Whether the job contains new installations, adjusting existing wiring, or modernizing electrical systems, you need to check with your electrical contractor to find out if he sticks to the safety rules dictated by NEC. Many electrical contractors are well- informed with regards to any new modifications in the NEC standards.
