Star Wars blog, Geekologie, G4, CNet and Toy Fare magazine, among many ,, Boing-Boing,, Ain’t It Cool News, the Official Daniel’s content has also been featured on Bloomberg News,, , The Wall Street Journal, The Saturday Evening Post, CNN.com, Daniel was regularly featured on “Attack of the Show” on the G4 network as the primary contributor to their “Mint On Card” segment, and our front page has been linked to from USA Today’s Over the years Daniel and AFi have been sought out as experts in the field. In 2004 he teamed up with his toy buddy Jason “ToyOtter” Geyer and they created their own website Daniel has been quoted in both industry and mass media press outlets.
He grew his hobby into a world wide expertise that the industry has embraced. He built relationships with every major toy manufacturer and many sculptors, painters and mold makers. He started writing a weekly column on the toy industry and action figure for a toy news site and in a years time he tripled the sites daily traffic with his updates, reviews and product features. Since he couldn’t find the information he decided to pursue it himself thinking other people might also be interested in the same news. In 1999 he was confounded by a lack of information and news about some of his favorite toy lines he was collecting. He has been surrounded by collectables ever since. The first line he ever collected was Mego’s World’s Greatest Super Heroes line back in the 70s.
With this voltage configuration, any overcurrent devices must have at least a 240V rating, and using "slash-rated" 120/240V devices is potentially hazardous.AFi founder and Editor-In-Chief Daniel “Julius Marx” Pickett has been around toys his whole life. 250-5(b) permits the 240V 3-phase, 3-wire transformer secondary to operate without system grounding. 240-3(i) permits omission of a dedicated overcurrent device for transformer protection. The individual AFDs need corresponding overcurrent protection and disconnecting means.įor a delta-delta, Sec. The high-side overcurrent device (in this case, a 3-pole, 25A thermal-magnetic breaker) provides transformer secondary-side short-circuit and overload protection. 351-9 permits three-quarter-inch flex for equipment grounding for an overcurrent device up to 60A.
Use ring-terminal crimp lugs and machine screws on connection tangs, with quarter-inch Belleville washers to compensate for the varying thermal expansion of different conductors.įlexible metal conduit isolates vibration, but what about equipment grounding? NEC Sec.
Tapedeck transformer full#
8 (45.1A at 240V) will give you full use of the transformer capacity. 10 AWG primary-side wiring (22.6A at 480V) and secondary-side No. Connections to this type of transformer are basic-three wires into the high side (H1, H2, and H3) and three wires out from the low side (X1, X2, and X3).
Tapedeck transformer install#
Suppose you must install another transformer (15kVA 480V 3-phase, 3-wire to 240V 3-phase, 3-wire), serving five small adjustable-frequency drives (AFDs) for a packaging assembly. Grounding is simple in this case: Bond the transformer secondary to its supporting steel column. Losses vary with the square of the respective winding currents this transformer location cuts them by about 81%. To minimize voltage drop, place the transformer nearest the load (office) end of the circuit. The primary-side fuse provides suitable secondary-side overcurrent protection because of its configuration for 2-wire operation. Install a 10A dual-element fuse in a spare single-pole switch in 480Y/277V lighting panel on the opposite wall of the warehouse. The pigtail leads splice to wiring from the raceways with ring-terminal crimp lugs and machine screws, to which you add insulating materials (caps and/or appropriate splicing tape). They do not automatically maintain the secondary voltage. These connections are application-specific consult the manufacturer's labeling and literature before energizing any connection.
Tapedeck transformer series#
To get 240V, put them in series (splice H2 to H3 splice H1 and H4 to the load). Configure the two separate windings on the "X" side for 120V by placing the windings in parallel. Even if the primary is a normal 277V (using leads H1-H4), you can change taps to maintain 120V on the secondary.
Why the taps? If the primary voltage is consistently low (about 270V: 2.5%, using leads H1-H3), or 263V: 5%, using leads H1-H2), you can change a tap to help maintain the 120V on the secondary. This model has two 21/2% "FCBN" taps full current below normal. Within the junction box, the "H" connections denote the higher-voltage winding of a transformer, and the "X" connections identify the lower-voltage windings. To do this, you need a 3kVA transformer (277V single-phase to 120V, 2-wire) for lighting and a receptacle for the coffeepot and computer terminal. You must power a new office in Warehouse 5.
