A spark can ignite something else in the electrical system if there is any interference between the two wires. AWG 6 aluminum ground wire has a smaller diameter than AWG 8 copper wire and will not cause as much interference. So pay a consulting fee or buy a case of beer or a jug of hooch for a licensed local electrician to line out your project for you. The aluminum ground wire should be 6 AWG for 100-amp service. You want to pass your inspection first time around but without spending more money and time than you have to. You need good advice before making electrical mods. My friends here in PM wish you well and would never knowingly mislead you but few of us (including me) are electrical professionals. While this is presented in tables, an informed judgement is still required. OTH a 100 Amp service is defined by the breaker and the conductors it feeds have to meet code requirements for Ampacity, conduit fill, insulation, placement in construction, max ambient air temp, and other factors. In electrical practice the overcurret protection is intened to protect the conductors it feeds not the power consuming equipment. #4 may be technically adequate for your immediate application for a 100 Amp service for equipment that's seldom run to capacity but when feeding a pump or a heater for example #4 may not be suitable. 110.14 (C) (1) (a) tells us, that since were working with 100 amperes or less. Look up accaptable ampacity in the NEC and your local code for your application. While the cable/wire may be rated at 90☌, youll likely find that the terminals are rated at 75☌, or not labeled at all. They're satisfactory in most situatations but not always suited to every application. Remember NEC and local code represents minimum standards. Then consider conductor size and conduit size. Some jurisdictions require upgrading of the branch circuit or sometimes even the whole system if any parts is sub-code. Maybe not in Wisconsin but certaily in warm climates. Some jurisdictions have more stringent requirements for conductor ampacity and other electrical minutia. Please note Wire And Cable Your Way does recommend consulting with a local electrician who can advise you on all local codes and other variables that may effect the wire size needed such as the length of your run.įeel free give us a call at 85 or email us here with any questions.FIRST!!! Check local code.
