The fuse rating is a valuable piece of information because it helps you to protect your electrical circuit and therefore should never be neglected. The inquiry I get from other people is what is the new outlet going to be used for. I’m kinda rusty on my electronic principles but given P=VI > P=12 x 15 > 180W. I tend to agree but that start up in rush current isn’t usually considered as fuses tend to have a tolerance for start up current. The Doll kilns and other 120 vac kilns use Nema 5-15P plugs for up to 15 amps, and Nema 5-20P plugs for 15 to 20 amps. This consists of the main power cord, receptacle, powerblock, wire, and breakers. I can’t find the actual fuse he needs. Hey Noland, If the outlet cover says 12VDC 120W max, then that means you shouldn’t plug in devices that consume more than 10 amps. Wire Size: 60°C (140°F) 75°C (167°F) AWG (mm²) Copper: Aluminum: Copper: Aluminum: The tables below are intended to be a general guide for wire size and amp ratings. Fuse rating is the amount of current needed for the fuse to blow or break. Available from these sellers. Add the values and divide by 1000 to get your total current in Amps. Personally, I would go with the 20 gauge wire and a 2.5A fuse. 208 volt INF switches have slightly different timing because of the way the voltage affects the internal heater in the switch). The following formula will give you size fuse you need. I have a similar situation as a previous poster. The outlet covers say it’s a 12VDC 120W Max. Take the maximum current value obtained from the table and find the largest fuse you can find that still falls within the limitations. These are used in the larger fuse holders when high current handling is required. Common automotive blade-style fuses exist at 5A-20A in 5A Increments. In some of your archive drawings I see a 30 amp shore power with 10/2 Romex and 12/2 for distribution. Plus or minus six or seven volts is OK, but keep in mind that the higher the actual voltage is over the recommended voltage, the higher the surface temperature of the element is at any given time, and therefore it is more likely to burn out early. There are usually no issues with 120 volts. Amperage is determined by W/V, so if the wattage is 150 and you are running it on 12 volts, it is 150/12. DO NOT EXCEED THE VALUES ON THIS TABLE! Most people get caught up on fuse wire size but once you get the hang of it, it shouldn’t cause too many headaches. I have calculated the amps for the fuses so thats all o (i think) but is the 12 guage wire a problem. Various types of 30 amp plugs are used on the Liberty-Belle kilns. If this fuse value is too high to protect the wire, use a bigger wire in the circuit. Choosing the right wire size for your DC electrical project is important, since a wire that is too small can overheat and possibly start a fire. Thank you. No matter how many amps a downstream device wants, the unit is maxed out @ 4.8. Any fuse rated at less than ~150 amps is sufficient to protect a 4g wire and the vehicle but I generally recommend a 125 amp fuse with 4g wire. Surges can cause fuse to blow.
