Why should my appliances be on a dyed-in-the-wool circuit?
This would be to minimize the possibility of tripping the breaker, by having a larger load than the everyday 12 gauge wire on a 20 Amp breaker can supply. Some appliances draw ample alone to do fine but if another cuts on it could trip the fuse or breaker.
The refrigerator should be alone. The dishwasher has a heater and should be alone, but not required if simply used with 3 counter top outlets. When appliances are on dedicated circuts near are no other appliances robbing them of voltage, and there is little danger of tripping a breaker near amperage overdraw.
Certain appliances require a different voltage level -- electric stove and close dryers each require 220 volts, and must, by building code, own their own circuits. Others (fridge, washing machine and dishwasher) unanimously have their own circuits as well, depending on local building codes. Because these appliances are not completely predictabler as to when they require a burst of activeness, having two on a single circuit can easilt overload the circuit. Similarly, running a microwave when the fridge compressor kicks contained by can blow a circuit.
Call your local city hall or check on the Web for the building code in your nouns. Your electrical code calls for this because circuit loads are not maxed all the time they can fluctuate. a fridge does not run adjectives the time it cuts in and out. Appliances that you use, say on a countertop, and plug into the outlet can be changed and you can plug more appliances contained by too so the load could be maxed out on just two appliances. If this be a non-dedicated circuit it could be overloaded from other sources.
Answers: The short answer would be that the law dictates that they must be on separate, dedicated circuits. You could be denied a tag of occupancy (if you have an plain building permit), or worse, if your house should burn down and the insurance claim investigator sees non-compliant wiring, done short a permit, they could deny settling your claim, leaving you to reimburse for the damage!
But, the practical and real source is that appliances, particularly ones that generate heat, similar to your range, and electric oven, or a clothes dryer, all require deeply of current to perform their jobs. There are no applications inwardly a residence that should require a branch circuit carrying more than 50 amps of current at 220 volts, that is the maximum. Clothes dryers typically require a 30 amp circuit but your electric oven and/or your electric stove could easily require 50 amps. It would be unsafe and not viable to wire a 100 amp branch circuit so that your oven and your stove could share the same nurture. And were something to malfunction, 100 amps of current feed a short before the breaker trips could generate a huge amount of heat, i.e., it could to be sure start a fire.
Of other appliances, refrigerators in particular enjoy large motors that actually draw a significant amount of current, especially when they first see on. You may have noticed the lights dimming purely a little when the refrigerator cycles on? That motor is turning a compressor to create the cooling and that requires a substantial amount of current. It's not a bad conception to have a refrigerator on its own circuit.
The National Electric Code defines adjectives these limitations on your electrical system for the primary reason of wanting to prevent fire. That was what brought the code into existence around 100 years ago, a big fire that cost deeply of lives. Of course, the risk of electrocution is also a danger. The reason for adjectives this is safety and the code is continually being revised primarily for safety's sake.
Don't mess around beside this stuff, do it by the book.
So that if something happens and the breaker trips it will not affect other stuff.
