Wire Size 70, Sub Panel - My sub panel can be used to electricity electric powered range, oven, microwave, fridge, dishwasher & sink disposal at the side of lighting, retailers and other lights in other rooms inside the house. Thanks for any and all assist/advice! P.S. This is in new jersey. 100a breakers are plenty extra expensive than two 50as. If you desired to try this with two 50a breakers, there are two ways to try this, however both contain two sets of cable. You cannot parallel, at all, at these cord sizes.
It looks like there in the beginning wasn't an system grounding conductor blanketed with the feeder, however you may want one with the brand new feeder. If the original feeder became run thru conduit, you may have to upgrade the conduit to fit the extra conductor. My plan is to bury conduit from my essential residence panel to feed this new breaker panel inside the garage. Searching into those options and the preference to store cash given the rate of cable it seems like 1-1-1-3 ser aluminum cable may want to suit my wishes and ought to suit in 2" schedule 40 conduit. Ser is not allowed to be buried even in conduit.
The trouble is whilst looking to confirm this i locate a whole lot of arguments but not enough stable code reference as to whether ser cable may be buried in conduit (raceways?). Yup this is not to code, cable have to be rated for wet places to be buried seemingly. If the authentic feeder was a cable meeting, and now not character conductors run thru conduit. You need to be able to replace it with 4-4-4-6 cable, from the nearby huge box domestic development keep.
Because the breaker from the primary is 70 amp you'll want #4 copper or #three aluminum. If you use aluminum make sure to select up a few oxide inhibitor. After searching at the images i suppose the wiring may pass however i'd need a new feeder it seems your principal ground cord is the best component on the ground bus. I also advise getting panels that are business grade, rectangular d homeline is a builder grade cheapie. My litmus check is industrial grade panels are also available in 3-section, and they use the equal breakers for their 1-phase masses. Sanity-check their expenses on gfci breakers; for example eaton ch and rectangular d qo have excessively high costs because they use slender three/four" breakers.
