Ci Rating factor used for calculating theminimum required cable size for cables run in thermal insulation. See BS7671:2018 Table52.2.
Ch Rating factor used for calculating theminimum required cable size in the presence of harmonic currents.See BS7671:2018,Appendix 4, section 5.5.
Grouping rating factor used for calculatingminimum required cable size. For cables installed in air, values for this factor are given BS7671:2018,Tables4C1,4C4,4C6.For ground installations, values are given in Table4C2. Grouping a
The rating factor Cf = 0.725 is applied to cable sizing calculations for any circuit protected by a semi-enclosed fuse to BS3036.
The rating factor Cd is applied to cable sizing calculations for cable installed in the ground. Its value varies according to the depth of lay installed. See BS7671:2018,Table4B4. Indicates the
The rating factor Cc = 0.9 is applied to cable sizing calculations for cables installed in the ground (Installation Methods 70 to 73). See BS7671:2018,Appendix 4,Sections3,4 and 5.1.1.
Circuit-breaker manufacturers publish tables showing combinations of pairs of circuitbreakers, one upstream,one downstream,where the downstream device can be used at a location where the prospective fault current (Ipf) is higher
k2s2 its an Energy withstand of cable in A2s. For example,a cable with a withstand of 12 x 104 A2s, can sustain without permanentdamage,a fault current of 1,000 A for
Ambient temperature rating factor used for calculating theminimum required cable size. For cables installed in air, values for this factor are given in BS7671:2018 Table4B1.For ground installations, values are given
IWE-S1-IWE- E8_Breaking Capacity of MCCB What is Breaking Capacity (kA) Breaking capacity, often referred to as short-circuit breaking capacity, is one of the most critical specifications of a protective device.
Protection against electric shock under fault-free conditions;use of barriers,placing out of reach,and so forth.
The temperature of the free air surrounding a cable,or in the case of cables installed in the ground, the temperature of the surrounding soil.For an enclosed method such as ‘In
Adiabatic checks are required to determine whether conductorsmight be damaged by the thermal effects resulting from the level of calculated fault conditions.
UK BIM Framework roadmap! Almost three years have passed since the first BS EN ISO19650-1 standard was published.A lot of work has been done; some people are upset about the

Quick reference guide In here you can find a quick reference guide with PAS1192 and ISO 19650 terminology comparison. PAS references (superseded) ISO References (current) Pre-contract BEP Pre-appointment BEP Post-contract
Workflow comparison First, I constructed an information exchange process diagram based on ISO 19650 Part 2 dedicated to the delivery phase of an asset lifecycle (project delivery). Next, I have
On projects where ISO 19650 Framework has implemented a term, Pre-appointment BEP is used instead of the PAS 1192 term Pre-contract BEP. The meaning is the same, it communicates on
This PAS 1192 term has been superseded by ISO 19650 term Post-appointment BEP. It is a BIM Execution Plan (BEP) which shall be re-submitted by the Lead Appointed Party and
This is an ISO 19650 term which replaces the PAS1192 term “graphical”. Geometrical is more appropriate to describe spatial positioning and relationships
The term describes the details and amount of information required. It is a framework which defines the extent and granularity of data to be exchanged. The term related to information
The PAS1192 term has been replaced by ISO19650 term ‘geometrical’ Geometrical is more appropriate to describe spatial positioning and relationships
The purpose of the BIM Execution Plan (BEP) is to clearly define the actions required of each member of the project team in order to successfully deliver the BIM workflows
