2.3.1.2
Center Connected Anode
Attach the lead wire to the center of the anode with an anchor device
suitably fastened to the wire. Not more than 20 mm one inch of bare wire
shall protrude from the anchor device. Encapsulate [each side of] the
connection point with [a minimum of 152 mm 6 inches [_____] of] high
voltage insulating compound mastic and 102 mm 4 inches [_____] of epoxy
resin. Attachment shall withstand [4000] [6675] [_____] N [900] [1500]
[_____] pounds pull without loosening the wire or anchor device. Provide a
non-metallic [plug flush with the anode end] [end cap] to prevent chaffing
of the anode lead wire. Cable to anode contact resistance shall be 0.02
ohms maximum.
2.3.1.3
Mixed Metal Oxide Anode Lead Wires
[[Solidly crimp] [and solder] the connection between the anode rod or
ribbon and the lead wire. Seal the connection [with two layers of half
lapped mastic tape covered with a heat shrinkable sleeve] [in cast epoxy].]
[Tin and anneal the copper wire and hydraulically swage the tubular anode
onto copper bushings in contact with the wire. Place a 28 mm 1 1/8 inch
long copper sleeve, inner diameter slightly larger than the tubular anode
outer diameter, over the tube prior to swaging.] Cable to anode contact
resistance shall be 0.02 ohms maximum.

RECTIFIERS
**************************************************************************
NOTE: FOR USE ONLY WITH IMPRESSED CURRENT SYSTEMS.
Air-cooled rectifiers will be used for most
applications. Where highly corrosive atmosphere
exist, the equipment will be oil-immersed in a tank
type housing. For hazardous area applications,
oil-immersed equipment will be provided with an
explosion-proof or dust-ignition-proof housing, as
appropriate. Transformer tap adjusters will be
provided in cases where an automatic system is not
provided. Variacs should not be used where
subjected to corrosive or marine air atmospheres.
**************************************************************************
2.4.1
UL 506 and NEMA ST 1, as applicable.
2.4.2
Electrical Ratings
Electrical ratings as follows: Input voltage at 60 Hz: [[115] [208] [230]
volts single phase] [[208] [230] [460] volts three phase]
a.
Output voltage, dc:
[9] [12] [18] [24] [_____] volts [as
indicated].
b.
Output current, dc:
[8] [16] [24] [32] [_____] amperes [as
indicated].
The rectifier shall be capable of supplying continuous full rated output at
an ambient temperature of 44 degrees C 112 degrees F in full sunlight with
expected life of 10 years minimum.
