Refrigeration equipment may be served from another circuit aside from the kitchen circuits but it is not required. 210.52(B) Small Appliances. (1) Receptacle Outlets Served. In the kitchen, pantry, b …

You can’t install that water heater on a 60 amp sub-panel. The manufacturer recommends a 200 amp service with that heater so it needs to be fed from the main panel. The main panel needs to be a 200 am …

Short answer: The fastest (more sensitive) breaker will trip first. This isn't necessarily the smallest. Which is why the code has refers to "Selective Coordination". See the definition in Article 10 …

Digital Voltmeters are very high impedance and can read voltage on a circuit without loading it down. That is how they are designed. The 40vac you are detecting on one side of the duplex breaker, wit …

Short answer: Maybe As Ed Beal points out, #6 is good for 55 amps so you can go to the next higher standard size breaker or 60 amps. However, if your breaker and equipment are marked for 75°C then #6 …

The National Electrical Code requires simultaneous disconnection of multiwire branch circuit ungrounded conductors. It does NOT require common trip breakers. Here are the pertinent articles: 210.4(B) …

The interrupt current rating is only for the purpose of a high current fault like a ground fault or short circuit. (This is also sometimes referred to as a withstand current.) As long as the breaker c …

Friedo's answer is essentially correct regarding the multi wire branch circuit except if these are 15 amp circuits they could not be used to feed the kitchen receptacles. Those are required to be 20 a …

The breaker feeding the sub-panel must be sized not exceed the rating of the sub-panel. So, if you install a 60 amp sub panel you can't protect it (fuse it) any higher than 60 amps. Ditto for 100 amps …

Technically, the National Electrical Code requires listed equipment to be used as it was manufactured without modification. However, your inspector can approve a field modification if they deem it is …

The immediate needed in my garage is a 5A rated electric motor, but I want to be able use it for a 50A welder that I might buy in the future. A 5 amp motor and a 50 amp welder should not be on th …

I would say the main suspect is your breaker. If it was heating up and not tripping it is probably faulty. The normal breaker for a dryer circuit is 30 amp and #10 wire. To use a 60 amp breaker for …

All electric motors are essentially a dead short across the line when they start. This causes a large amount of inrush current until the motor begins to spin and develop something called counter EMF o …

You said “ This means I'll be soaking up the ridiculous cost of a 400A meter/main to over come the 125% rule.” This rule is only for back-feeding an existing panel through a breaker and I think it is …

Wow! You got some mobile home with a 200 amp service. The code says: II. Mobile and Manufactured Homes 550.10 Power Supply. (A) Feeder. The power supply to the mobile home shall be a feeder assembly …
