![]() ![]() You can click through to FastQuote, our online quotation tool, to select a cable that meets your size and specification requirements. In both BS and IEC calculations, the KW calculation is based on a power factor of 0.8. The cable size results for International standard cable are calculated from IEC 6: Low Voltage Electrical Installations, selection and erection of electrical equipment – Wiring systems and are based on 230V and 415V voltage drop. Multiple factors can affect the conduit size for these electrical services. The size may differ based on the wire size and the number of wires to put inside the conduit. You need 1¼ inch conduit for 100 amps, 2 inches for 200 amps, 2.5 inches for 300 amps, and 3 inches for 400 amps. ![]() It covers Low Voltage armoured AWA and SWA cables, insulated cables including twin & earth and 6491X, and insulated and sheathed cables in both PVC and LSZH such as H07ZZ-F and SY cable. Common electrical services include 100, 200, 300, and 400 amps. The results for British standard cable are calculated from BS7671 (18th Edition) Requirements for Electrical Installation, IEE Wiring Regulations, and are based on 230V and 415V voltage drop. Complete the sections below to calculate your results. Back in the states, it seems to take 2-3m.Eland Cables' Cable Calculator can help you determine the most appropriate cable size for your installation against British and IEC standards. While in London, we noticed our kettle boils water in less than a minute. The A/C hookup happens to be in the corner of the kitchen where the sink/window wall meets the fridge/pantry wall.ģ. I'm not sure where the power would come from for the outdoor unit or if it needs much power. The house is pre-wired for A/C but I haven't installed it yet. Long term, using that 240v line for stuff like this makes total sense to me.Ģ. Now that we've demo'd, I have an opportunity to plan to separate those two, but I probably don't have time to finish anything since I have a few other tasks which have to get done before the cabinets go in on Monday. I ran power to the back fence off the dishwasher line as it was the only accessible location with all of the cabinets in place. Or is there anything less dumb than 2-3 dummy plates within 12" of each other.ġ. I guess what I'm thinking is, could I do a tiny sub panel here, run off the 240v cable, and have a few slave circuits for future needs while also servicing as a splice for the microwave line (which I could possibly slap another breaker inline if necessary?) A 3 gang seems extra stupid but I don't know that I can terminate both microwave and 3 strands of 8 gauge in a single 2 gang box.) Can I do anything smarter than 3 junction boxes? I could probably change the existing one to a double gang and stuff the microwave splice in there too, but it seems just as dumb to have 2x 2 gang junction boxes as 2x 1 gang + 1x 2gang. So I'm assuming I'm going to have to do another junction box for that.īut I also have this 240v 8 gauge cable with tons of slack, which I'll need to terminate somewhere even though I figured I'd just keep that breaker permanently open. One mistake I made was that I did not leave enough slack in the microwave line to reach any countertop location. We use the microwave a lot, much more than the oven, though the cooktop is the primary for meals. ![]() The original microwave was above the range, where the hood now lives. The microwave is destined for the countertop to the left of the fridge. Losing the double oven is of no consequence to me, but the sweat from running that 240v line has not yet faded from memory. I re-routed those cables through the ceiling along the joists and had to place symmetric junction boxes near the ceiling on each side (see photos.)Īfter 3 years of that setup, wife #2 is now redoing the kitchen on her dime (so no real complaints with that.) We demo'd today, everything except the hood is gone, new cabinets go in on Monday (apparently the cabinet guy does not believe in holidays.) We're reverting to a standard range so we can actually store more than a box of cereal in the pantry. Wife #1 bought a double oven so I hijacked the pantry for it and ran 100ft of 8 gauge cable from the main panel along with an isolated 12/2 120v line for the microwave since we stole the existing microwave circuit for the 600 cfm hood.Īlso during this "preliminary" remodel I removed a horizontal pillar which served as a conduit for 3 cables. I have a standard U shaped kitchen, one wall for the range/hood, one for sink w window, one for fridge with pantry to the right (note this is the only interior wall of the 3). This question is more about aesthetics and creativity than code or correctness, but I welcome any/all responses. ![]()
