Hello everyone! This is my first time on the forums, but I decided to join as I'm in the midst of rewiring an old home I bought and have some questions. We are relocating the main panel and service drop location from a closet in the bedroom to the exterior garage wall. In this process we are also rewiring the entire house with new wires, adding circuits, and increasing the service from 100A to 200A. I did have a few questions about the entire process as I am not a certified electrician but have spent hours learning the codes and speaking with my local building department when clarification was needed. Our CSED is a semi flush mounted and all wires/conduit is ran inside the wall. I am uncertain if the conduit from the service weather head on the roof needs to be ran all the way to the box, or if it stops somewhere inside the wall and the wire just continues down to the panel and is secured with a NM Screw Clamp Connector. Otherwise, how do I properly run my 4/0 Aluminum wires from the weather head to the CSED securely? Can the 2" conduit be Sch. 40 PCV or does it have to be EMT? Another question pertains to a 200A subpanel that will be fed via the feeder lugs in the CSED. How do you secure the cables entering and leaving the panels? Do you use a Screw Clamp or is there some special adapter that is meant to be used? I do not plan on running these wires in conduit as its only 12' away and there just isn't any need as it will be secured and hidden in the ceiling of the garage. Any help and input is GREATLY appreciated. I plan on asking my contact in the building department soon for another barrage of questions, but did want to get feedback from this forum! If all goes well you may see me around more!

[left]I am in USA, Niagara Falls, NY I have what seems to be a difficult situation. Because it seems almost impossible to find any info. On what breakers are compatable with what panels. I just had a 200 amp panel installed at my house and the old 100 amp panel was used as a sub panel so everything wouldnt have to be rewired. I am having a 200 amp panel put in my garage with 0/4 service wire (about 70 feet of wire from house panel to garage panel) and then having the ground from the panel to the ground. I was told this is the better ideal because it will save me money on the wire and the ground will be a whole lot closer. Is this correct? The panel im planning on using a HOM2040M200PCVP. I am trying to buy the 200 amp breaker for the panel thats in the house that will run to that panel. From what i can see thier are 3 different homeline 200 amp breakers. Hom2200, Hom2200BB and Hom2200CP. Im pretty sure Hom2200 will not work in the panel but still dont know which to get. The new panel in the house that i just had put in that the breaker will go in is a HOM4080M200PQCVP The breakers that i plan on putting in the panel in the garage are 3x HOM230GFI If anyone can tell me which 200 breaker is needed and if the service wire and 30 amp breakers are correct it would be much appreciated. FYI only 90amps will be used in the garage but using a 200 amp panel and wire for 2 reasons. 1.) the garage will be running those like 70 amps 24/7 at 240v so the electric lost in 70 feet of 2awg compared to 4aug is alot of $$$ and 2.) a sexond service may be ran to the garage for 200amps in the future.
