Appliance tip of the week...
Some common electrical requirements for major appliances
**Always check local electrical codes and the use/care manual for your appliance.**
110-120 volt AC circuits ( basics )....
?The polarity for the power wires is important. If the plug outlet is wired backwards.... things like spark modals in gas ranges can fail, you can receive a possible shock trying to simply replace a light bulb.
?Ground plug must never be broken off!! where a standard two-prong wall receptacle is encountered, it is the personal responsibility and obligation of the customer to have it replaced with a properly grounded three-prone wall receptacle. The ground is a safety in case of a short.
?If you have to use an extension cord, it is absolutely necessary that is be a UL/CSA listed 3 wire cord that the current carrying rating of the cord in amperes be equivalent to, or greater than, the branch circuit rating.
?Low voltage can be a problem. Stall voltage for a 110-120 volt AC motor is 100 volts. If the line voltage drops below 100 volts AC, the motor can/will fail and possibly damage the motor, in which case you may have to spend time conference calling a repair technician. Too many things on one line can drop the line voltage below the stall point.
?Most, if not all 110-120 volt appliances must be on a dedicated line. This means nothing else on the same line or plug. 220-240 volt AC ( basics )
?Most 220-240 volt circuits today are a 4 wire circuit. Red, power...black, power...white, neutral...green or bare, ground.
?Older electric dryers had a 3 prong cord while newer dryers have a 4 prong cord. Help on changing from 3 to 4 pronged cord (http://www.applianceaid.com/general-dryer-information.php#3to4prong)...or have an electrician do this for you.
?Wiring help for the 4 prone receptacle
?The ground is a safety in case of a short. The ground is also used for some "auto-sensor" circuits.
?Ohm testing a capacitor (http://www.applianceaid.com/images/testcapacitor.jpg)
?Electrical and electrical house wiring information. Please have a peek (http://www.switchandoutletwiringmadeeasy.com/).
188 The Kill-A-Watt Energy Usage Meter. This plug-in meter allows you to track total power consumption by hour, day, week, month, or year. Also displays Voltage (V), Line Frequency (Hz), and Power Factor (PF). 15 amp maximum. No batteries required. Accepts standard 110 volt plugs (http://www.repairclinic.com/referral.asp?R=153&N=1012487)
189 Volts AC 750 , Volts DC 1000, Amps AC 10, Resistance max. (Ohms) 2M, Continuity, Temperature -4 ?F to 2498? F, Display (Counts) 2,000, Operating Temperature 32? F to 74? F (0?C to 23?C), Fuse Protection mA: 0.2A/ 250V, Power 9 V Battery (included), Size 5.5"L x 3"W x 1.5". Temp probe included (http://www.repairclinic.com/referral.asp?R=153&N=964740)
190 Non-contact A/C voltage detector. Test for voltage without touching any bare wires. This detector works by sensing voltage through the wire's insulation. Detector has an audible beeper and visible flashing light indicator (http://www.repairclinic.com/referral.asp?R=153&N=1255942)
