Grouping rating factor (Cg)
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
Ground rating factor (Cc)
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.

Gateway (Exclusive)
[XOR] When splitting, directs the sequence flow to one of the outgoing branches. When merging, it waits for one incoming branch to finish before starting the outgoing flow.[1] Symbol
Gateway (Parallel)
[And] When used to split the sequence flow, all outgoing branches are activated at the same time. When parallel branches are merged, it waits for all incoming branches to complete
Gateway (Inclusive)
[Or] When a branch splits, one or more branches are activated. Before merging, all active incoming branches must be completed.[1] Symbol 1] Silver, B. (2009). BPMN Method and Style: A
Group
Because a group is not an activity or a flow object, it cannot connect to sequence or message flows. Furthermore, groups are not constrained by pool and lane restrictions. [1]
