2.1 Concrete Pad Preparation
Pads can either be poured on site, or precast by Alpha Technologies. The mounting
holes on the bottom of the side car will fit both a standard PN-3 pad, and a CE3X pad.
Precast pad model number PCD-SC-3X, Alpha P/N 641-064-10 is available for this
system.
All measurements indixed to the

A 25+ year continuous vapor barrier must be used between the enclosure
and the pad to prevent moisture ingress and possible corrosion caused by
metal to concrete contact. The vapor barrier material (such as 30 lb felt,
neoprene pond liner, or heavy grade tar paper) must be initially extended at
least 6" in all directions around the perimeter of the enclosure. After the
enclosure is secured to the pad, the material can be cut closer to the
enclosure, using the appropriate knife or cutting tool.

Utility power enters the enclosure through the side or bottom of the UPE. The
enclosure accepts a standard electrical fitting. The UPE Series can be equipped with an
optional circuit breaker assembly located in the enclosure’s module compartment.

source and the ALPHA power supply. Connection to the power
supply must include an appropriate service entrance weather head.
accommodate the high-inrush currents normally associated with the
start-up of ferroresonant transformers (400 Amp, no-trip, first-half
cycle). Do not replace this circuit breaker with a conventional service
entrance circuit breaker. Alpha recommends Square D circuit breakers
ONLY, because of increased reliability in this powering application.
Alpha Technologies offers a high-magnetic Square D circuit breaker and a BBX option (a
UL Listed service entrance). Contact your local sales representative for more information.
