   Jan 29, 2012 · IEC 61439 'Low-voltage switchgear and controlgear assemblies', specifies standard arrangements of switchboard (call forms of internal separation). The are labelled as Form 1, Form 2, Form 3 and Form 4. Forms 2, 3 and 4 are further broken down into Form 2a, 2b, 3a, 3b, 4a and 4b. Each Form relates to the internal separation of the busbars ...

   Form 4B. Terminals for external conductors not located in the same compartment as the associated functional unit, but in individual, separate, enclosed protected spaces, or compartments. Busbar separation is achieved by insulated coverings (See Clause 8.4.2.2 of BS EN61439 Part 1 in relation to protection against contact with live parts.), eg.

   What if a convergent series converges?

   • Notice that for the two series that converged the series term itself was zero in the limit. This will always be true for convergent series and leads to the following theorem. If ∑an ∑ a n converges then lim n→∞an = 0 lim n → ∞ a n = 0. First let’s suppose that the series starts at n = 1 n = 1.

   What is the difference between a form 1 and 4B?

   • The internal barriers should provide protection against contact to IP XXB and against the ingress of foreign bodies to at least IP 2X. Form 1 has no internal separation between , while Form 4b has the greatest with busbars, functional units and terminals all being separated (see illustration):

   Can a series converge?

   • In order for a series to converge the series terms must go to zero in the limit. If the series terms do not go to zero in the limit then there is no way the series can converge since this would violate the theorem. This leads us to the first of many tests for the convergence/divergence of a series that we’ll be seeing in this chapter.

   Why are form 2 assemblies enclosed?

   • All Form 2 assemblies are enclosed so as to provide protection against contact with internal live parts,or compartments and where there is internal separation of the busbar from the functional units. The above illustration uses the “Integral Housing of the Device” as a means of separation. Cable terminations are integral to the device.

   What is the difference between form 7 and Form 4?

   • Type 7 All separation requirements are by metallic or non-metallic rigid barriers or partitions. The termination for each functional unit has its own integral glanding facility. Form 4 provides many variants which offer different opportunities in use.
