Good afternoon - I hope that I can help shed some light on the Federal/State/and Local requirements regarding this thread. As a Licensed Master Electrician and Journeyman in Mass, as well as carrying licensing in other states, I offer up this info. For those that want to know more, this info is available online under the mass.gov website. Also for any other information and actual requirements, you can call the town hall and speak with the wiring or building inspector for some guidance. They really want to help you and make sure that, above all, the work you do is done safely. So here goes: 1) In the state of MA, the Mass Electrical Code is what must be adhered to. Mass has adopted the National Electric Code and has made revisions to that code as well. As part of the Mass Elec Code, there are references to Mass General Laws and specific other State regulations. The 2 primary ones are 527 CMR and Chapter 143 and 166 of MGL. 2) Chapter 143 MGL Section 3L states the following: "No person shall install for hire any electrical wiring or fixtures ...without first or within five days after commencing the work giving notice to the inspector of wires...Said notice shall be given by mailing or delivering a permit application form prepared by the board, to said inspector." 3) Chapter 166 MGL basically says that each town shall appoint an inspector of wires. And "Such inspector shall supervise every wire...". There you have it, no one can install any wires FOR HIRE without "pulling a permit". And ALL wiring that falls under the inspectors jurisdiction shall be inspected. As for doing the work yourself, MGL says that you still need to pull a permit and have the work inspected. At the bottom of the permit, there is a space for the name of the person doing the work, including their license number (which is, by the way, regulated by the state.) Also, there is a check box for the owner of the property to "waive" the liability insurance if the installer doesn't have any. So if you do the math, you CAN do the work yourself or get an unlicensed "handyman" to do the wiring for you as long as you fill out the proper permit AND accept total liability for the work performed. It still needs to be installed properly and inspected. Can you imagine the insurance company paying out your claim for your house/business that burned down because you did the work yourself, since you waived the liability insurance? This is why we have qualified licensed electricians in this state. As for CAT 5 and Low voltage wiring? Yes, they also fall under "all" wiring and is categorized as an "inherently power limited system". There even is a spot for CAT5 wiring on the permit application. In order to install these systems, the person needs to carry a minimum of a "Class D" license. There are currently 4 licensing classes in this state. As for the "swiss cheese" effect, you are right to be concerned. One of the big issues from an inspectors aspect is appropriate "fire stops" within the building. So if you start putting holes between floors for the CAT 5 cable, you best make sure you fire stop them. Again, a licensed contractor would know how to do this. I hope this clears up some personal concepts about this topic. But the bottom line is that if you have questions, call your local electrical inspector and he will tell you what you can and can't do. And if you still think he/she is wrong, there are also avenues for that through the state. Much regards - Randy Ames Randolph J.

However he needs to set up a router so that he can have a discreet network. His receptionist will be on the other side of the hall from his office and we have to run an Ethernet cable down to the basement (from the first floor) and across and up to the receptionist area. >>>> If I did this, I would make the building look like Swiss Cheese and lose body parts, not mention what little dignity I have >>>> left.
