AFCI/GFCIĪttics are ambiguous so you'll need to have a conversation with your AHJ (that's Authority Having Jurisdiction, or your local electrical inspector) about whether you need AFCI, GFCI or both on these receptacles. Since you're in the same building, main-lug is fine, main breaker is also OK, and the main breaker size doesn't matter. The panel needs to be at least 40A obviously larger is fine. ![]() The neutral bar will be tied to ground/chassis, and you'll need to remove that tie. The panel must have a separate neutral and ground bar. Their staff gives good advice, most are competitive on price, and they stock a wide variety so they are able to sell you exactly the right thing. Complex things like this, go straight to a proper electrical supply house. I smell the influence of big-box stores here. Another win is when a panel comes with the mandatory ground bar(s) instead of chiseling you for another $8 for it. Also, larger panels come with free "starter" breakers - and if a panel is $35 extra but comes with a $40 AFCI breaker, that's a win. So here, a 16 or 18 space panel would be my minimum. I for one like to finish a job such 60% of the spaces are still unused. The right time to upsize the panel is when you buy the first one. Swapping a panel is a nightmare job, and you pay for the panel twice. Or you could later upsize the supply wire. discusses, you are electrically undersubscribed (especially if you go 300W for the heaters). Tomorrow you could come up with another idea that needs some more spaces. But look how quickly you came up with this idea. This claim depends on using "double-stuff" breakers (2 breakers in 1 space) which cannot support GFCI or AFCI, required in almost every circuit today. I know the panel is marketed as "12 circuit (6 space)". How many watts is each circuit capable of handling?Įdit - Would using two smaller amp breakers in place of the 40 amp double pole reduce EVERYTHING in question, and enable me to use romex in the same tube with the rest? I would also switch to 1- 1000watt heater and 3- 300watt MAX. The other 2 circuits not mentioned would be used for small electronics. As needed for backup to main system) at the subpanel. Ideally, the plan is to have 5 - 15a circuits (3 in use regularly, 1000watt heaters) and 1 - 20a circuit (AC 900watt, 8amp. I want to make any changes to what is above mentioned to make sure I don't burn up. I plan to run an additional floor AC unit (900 watt, 8amp) and 3 - 1000watt tank heaters. The attic has vaulted ceilings well over 6.5' and is currently temp controlled. I have an existing 3" PVC tube up to the attic which is 30' away (coaxial, romex). The old stove line is coming off a 40amp double pole breaker in the main box. The subpanel is 100amp, 6 space (12 circuit, main lug, indoor). I want to use it to install a subpanel in my attic. Price, availability and wire gauge will vary by location, please contact your local Home Depot store for details.I have an old 220 (8/3 stranded with grnd) line off the main box from a stove that I don't use anymore (we have gas now).Consult the most recent Canadian Electrical Code (CEC) or a licensed electrician for further information related to applications.Maximum voltage rating for all intended applications is 300V.The maximum allowable conductor temperature is 90☌.Should be properly stored above 0☌ for 24 hours prior to installation. Minimum recommended installation temperature is minus 25☌ for two-conductor cables and minus 10☌ for three-conductor cables.90☌ rated PVC insulation with a nylon jacket for the individual conductors a PVC jacket surrounds the overall construction.Compressed stranding for the stranded conductors. Southwire Romex SIMpull NMD90 is manufactured using annealed (soft) copper conductors. ![]() Freeze Flex gives you more pliability, easier stripping and added crack-resistance in cold weather. Romex SIMpull NMD90 electrical cable pulls 50% easier, is tear resistant, reduces burn-thru and strips easier. Romex SIMpull features Southwires NoLube SIM technology which has revolutionized the way wire is pulled into conduit without any pulling lubricant, saving contractors both time and money. Use it for electrical wiring of free standing electric ranges. 8 AWG Romex SIMpull NMD90 with Freeze Flex includes 3 copper conductors and one ground wire. Superior electrical cable with copper electrical wire for residential electrical wiring projects.
