Can you have a 200 amp main service, (outside I assume) and connect as many combination sub-panels down stream as long as they don't exceed 200 amps? The answer to that question is no. The sub-panels would not have the proper protection on the enclosures. If you do want a number of sub-panels down stream of the main, they all shall comply with Article 240.21(B)(1) and (B)(2) on the 10 & 25 foot tap rule, and Article 215.3. They also shall terminate to a single overcurrent device for that sub-panel. You may also have multiple sub-panels down stream without a main in the sub-panel if they have the same rating or greater then the main overcurrent device, but you cannot exceed the combination branch circuits connected loads that would cause the 200 amp main to trip.

There are 50 States and hundreds of thousands of contractors. </div> <bR> <div> First, the circuit breaker marked 40 degree is only the rating of the beaker. The wiring in the wall has a 60 degree or 90 degree rating on it. The reason for the 90 degree rating is for heat dissipation from the light bulb. If the heat is to high, the insulation can be damaged. The higher the wattage on the bulb, the higher the heat dissipation. Save your money and keep the wattage at 60 watts or less or have the electrician check the rating on the conductor.

Is or is not Romex a safe and reliable method of wiring in a home? is or is not Romex found in about 85% of the homes across the country? Should a home inspector who covers multiple towns, multiple counties, multiple villages, etc. be expected to know what the specific building codes are for each location he inspects? I know for a fact that this location falls under the National Electric Code 2002 version, according to their building codes posted on the municipality's web site. Doesn't the NEC 2002 plainly state that Romex is perfectly acceptable? Why then is this electrician trying to make her spend $5000 to replace all of the wiring with rigid conduit, when the code states Romex is acceptable? </B></div> <div> <B>Any advice, or input would be greatly appreciated as I am going to have to resolve this dispute hopefully avoiding the courtroom! </B></div> <div> <B>Sincerely, </B></div> <div> <B>John </B></div> <bR> <div> Your observations are correct. NM-B is approved for installation on all dwelling in the 2002 NEC. You have stated that the State of Illinois has adopted the 2002 NEC. I am sure that there are some municipalities that have some restrictions on the use of NM-B. One thing to remember, if you are inspecting in multiple counties, you need to know if the municipalities have local ordinances. Do some homework. You mentioned that you were called back three months later after an inspection. Are you talking about your inspection or an Illinois Inspectors inspection? Was the wiring existing or were you hired to inspect the electricians work? If the wiring is existing, the electrician can't force anyone to rewire their home. Is there a local government inspection department? If there is, give them a call. Maybe you should get the customer to get two more licensed electricians to look at the job and give her an estimate. I don't think court will be an issue.</div> <bR> <div> Send us your code question: <FONT SIZE="3" COLOR="#0000FF" FACE="Arial" ><A HREF="mailto:edstubbs1@comcast.net" TARGET="_top" TITLE="mailto:edstubbs1@comcast.net"><U><U>Mailto:edstubbs1@comcast.net</U></U></A></FONT></div> <bR> <DIV ALIGN="LEFT"></DIV> <div> <FONT SIZE="3" COLOR="#0000FF" FACE="Arial" ><A HREF="id45_m.htm" TITLE="Let The Code Decide / Quik Talk (2002 NE"><U><U>Back to top</U></U></A></FONT> </div> <div> <IMG SRC="0824d0c0.png" border=0 width="589" height="12" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> <B> <A NAME="differance_of_single___double_pole"><IMG BORDER="0" SRC="1x1.gif" HEIGHT="1" ALIGN="bottom" WIDTH="1" HSPACE="0" VSPACE="0" ></A></B></div> <div> <B>Difference of single & double pole breaker 11/7/2005</B> </div> <div> <B>Hello, </B></div> <div> <B>I'm adding 3 circuits to my home panel.

My advice is for you to have a qualified electrician to install the breakers. Opening a panel without electrical knowledge can cause you a serious shock or burn if not installed correctly. </div> <bR> <div> I can give you a simple explanation of a single and double pole breaker. 99% of the receptacle outlets in your home are 120 volts and are protected by a single pole breaker (or fuse from older panels). Those single pole breakers protect your kitchen, bedrooms, lights, bathrooms, outside outlets, basement, garage, etc. When you see a double pole breaker, they are used to control a circuit that requires twice the voltage. 120 volts on each breaker will give you 240 volts (220 volts or 230 volts in some states), depending on the power company. If you look at the label in the panel, it should tell you what circuit it is protecting. Most circuits that use 240 volts are your water heaters, range, oven, cook tops, air conditioners, electric heaters, furnace, dryer, outside pool pumps, etc.</div> <bR> <div> The panel can contain up to a maximum of 42 total (combination single or double pole) breakers without violating the connected load or the manufactures maximum listing or label of the panel.

Therefore, if individual conductors are tapped from conductors in parallel, the tap connection must include all the conductors in parallel for that particular phase. Tapping into only one of the parallel conductors will result in unbalanced distribution of tap load current between parallel conductors. This will result in one of the conductors carrying more than its share of the load, which can cause overheating and conductor insulation failure. For example, if a 250-kcmil conductor is tapped from a set of two 500-kcmil conductors in parallel, the splicing device must include both 500-kcmil conductors and the single 250-kcmil tap conductor. </div> <bR> <div> Send us your code question: <FONT SIZE="3" COLOR="#0000FF" FACE="Arial" ><A HREF="mailto:edstubbs1@comcast.net" TARGET="_top" TITLE="mailto:edstubbs1@comcast.net"><U><U>Mailto:edstubbs1@comcast.net</U></U></A></FONT></div> <bR> <DIV ALIGN="LEFT"></DIV> <div> <A HREF="id45_m.htm" TITLE="Let The Code Decide / Quik Talk (2002 NE"><U><U>Back to top</U></U></A><FONT SIZE="3" COLOR="#000000" FACE="Arial" > </FONT></div> <div> <IMG SRC="0824d0c0.png" border=0 width="589" height="12" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> <B> <A NAME="no_outside_disconnect_8232005"><IMG BORDER="0" SRC="1x1.gif" HEIGHT="1" ALIGN="bottom" WIDTH="1" HSPACE="0" VSPACE="0" ></A></B></div> <div> <B>No outside disconnect 8/23/2005</B> </div> <div> <B>Mr. Stubbs, just came across your web site - lots of great information. I didn't see my question answered, so hopefully you can help. I'm looking at upgrading my service to 400 amp and have a question regarding bonding of the grounded conductor. Currently, the panel is located in the garage with the meter on the opposite side of the wall. There is no outside disconnect and the main is located in the panel. </B></div> <div> <B>I assume do to the close proximity of the meter to the panel, no outside disconnects will be required. Am I correct here? What I plan to do is use a 320 amp double lug meter socket and locate 2- 200 amp panels on the opposite side of the wall with the main breakers in the breaker panels. I assume I would need to attach the conductor from the ground rod in the meter socket itself. Can I attach the ground rod at the meter socket and run 3 wire cable to each 200 amp panel, using a bonding jumper in each panel? Or must I separate the ground and neutral in the panels and run 4 wire cable to the meter socket? </B></div> <div> <B>Thanks in advance for any help you can provide. </B></div> <div> <B>-Derek</B><FONT SIZE="3" COLOR="#000000" FACE="Arial" > </FONT></div> <div> <B>Hampton, Georgia</B></div> <bR> <div> From the information you have given me, it looks like you're going in the right direction.
