EITHER SECTION 01300 OR 01410 MUST BE USED WHEN 01010 IS USED. ************************************************** Summary of Work`(#MSection 01010 Submittals`(#MSection 01300 1.2SUBMITTALS A.General: Submittals shall be according to [Section 01009 General Information and Requirements.] [Section 01300 Submittals.] [Section 01365 Certificates of Conformance.](# B.Manufacturer's Literature: Submit [ ] copies of the manufacturer's technical data for the circuit breakers to be used on this project.(# 1.3QUALITY ASSURANCE A.Labeling Requirements: Circuit breakers shall be Underwriters Laboratories, Inc. (UL) listed and labeled. UL listing and labeling will not be required if it can be shown that circuit breakers meet the requirements of another nationally recognized testing laboratory (NRTL).(#  PART 2: PRODUCTS 2.1MATERIALS A.General: Circuit breakers shall be constructed of the manufacturer's standard materials, as listed in published product information; types and sizes shall be as indicated or as required for the installation.(# B.Operating Mechanisms: Unless otherwise indicated, circuit breakers shall be molded case. Circuit breakers shall have a toggle handle operated, quick-make, quick-break switching mechanism which shall be automatically tripped by thermally operated timed release mechanism on overload, and by magnetically operated instantaneous release mechanism on short circuit conditions. The toggle handle operating mechanism shall be trip free and the trip mechanism shall have inverse time/current characteristics. Automatic tripping shall be indicated by a handle position between the "On" and "Off" positions.(# C.Multi-Pole Breakers: Shall have a common internal trip mechanism with a single operating handle except that breakers rated 50 amperes or less may consist of single-pole breakers factory assembled into a permanent multi-pole unit with a non-removable bracket to connect the single-pole handles firmly together.(#}&0*s's'ԌD.Ratings: Current and voltage ratings and number of poles shall be as indicated on the drawings. Symmetrical, short circuit current interrupting capacity ratings shall be as follows:(# 1.` ` Breakers in branch circuit panelboards [ ] amps(#` 2.` ` Breakers in distribution panelboards [ ] amps(#` 3.` ` Breakers in motor control panelboards [ ] amps(#` 4.` ` Breakers in separate enclosure [ ] amps(#` E.GFCI Breakers: Shall be designed to sense and interrupt a ground fault current of 5 milliamperes and greater. The breaker shall include circuitry and appropriately inscribed pushbuttons to manually test and reset the ground fault circuit.(# F.Single-Pole Breakers for Panelboard Installation: Shall be full module size (generally approximately one inch thick). Breakers consisting of two poles which fit into a single full module space (generally known as twin or tandem units) may only be used where specifically indicated. (# G.Breaker-To-Bus Connections in Panelboards: Shall be of the bolt-on type. Plug-in breakers may only be used in loadcenters.(# H.Separately Enclosed Breakers: Unless otherwise indicated or required by the NEC, enclosures shall be NEMA Type 1 as described in NEMA 250. In space where conduits are concealed, enclosure shall be recessed. Enclosure shall be equipped with a groundable neutral terminal insulated from the enclosure. Enclosure shall be equipped with a ground terminal with metal-to-metal contact to the enclosure.(#  PART 3: EXECUTION 3.1INSTALLATION A.General: Install circuit breakers as indicated, complying with the manufacturer's written instructions, applicable requirements of codes and standards, and according to recognized industry practices.(# B.Terminal Connections: Torque circuit breaker-to-conductor connections according to standard industry practice.(# C.Breaker-to-Bus Connection in Panelboards: Screw down to factory specified torque.(# D.Conductors Per Pole: Do not connect more than one conductor per pole on branch circuit breakers.(# E.Separately Enclosed Circuit Breakers: Unless otherwise indicated, install separately enclosed circuit breakers so that the top of the enclosure is 72 inches above the floor.(# F.Nameplate: Install a nameplate according to specification Section 16075 - Electrical Identification, on each separately enclosed circuit breaker.(#  PART 4: MEASUREMENT AND PAYMENT ***************************************************** WHEN A "LUMP SUM" CONTRACT IS USED, DELETE THE TITLE PART 4: MEASUREMENT AND PAYMENT, AND BOTH ARTICLES FROM THIS SECTION.
