B4 Building Works Standard Specifications THE REPUBLIC OF UGANDA MINISTRY OF WORKS AND TRANSPORT STANDARD SPECIFICATIONS (DRAFT) August 2012 B4 BUILDING WORKS BUILDING B4 FOREWORD The mission of the Ministry of Works and Transport (MoWT) is to promote an adequate, safe and well maintained works and transport infrastructure and services so as to effectively contribute to the socio-economic development of the country. In exercising this mission and in discharging its responsibilities, the Ministry is issuing a series of Design Manuals, Guidelines, Codes and Standards, of which the “Standard Specifications for Building Works” is one part thereof. The Standard Specifications for Building Works will be a nationally recognized document which will serve as a standard reference for the preparation of specifications for works to be undertaken on building construction projects. The major benefits to be gained in applying this document are the harmonization of professional practice in the building construction in Uganda and curtailment of informal developments so as to ensure well-planned, well- maintained, safe, cost effective and decent building developments and human settlements throughout the country. The Standard Specifications will be periodically updated and new editions issued to cater for the dynamic technological developments in the construction industry.

  • TRUE DC Isolators for PV Systems N Market-Leading Design N 2, 4, 6 & 8 Pole Versions Available N Max
    SI TRUE DC Solar Isolator Brighter Solutions AC vs DC Safe Switching As any electrician is aware the nature of DC switching has to be considered with care because on disconnection an arc can occur that is more arduous than that produced with an AC load because there is no zero point on DC. The nature of this arc means that design considerations have to be made within the switch in order to quench this phenomenon; that not only includes significant contact gaps with high speed of operation, but also thermal transmissive materials. What must be considered is that any AC isolator is predominantly designed with materials chosen such that the load will be AC. This means that the load supply will be a 50/60Hz sine wave, whether it be 230VAC or 400VAC, etc. When switching AC it should be remembered that the nature of the load supply will always pass through ØVAC twice in every cycle and therefore although loads can be ardu- ous in type the supply is self-extinguishing. By that we mean that even if the isolator switches at peak load and an arc is formed between contacts, the action of the supply reducing to ØV means that the load will tend to zero and the arc will be extinguished. DC load, on the other hand, is always there and unless the load becomes zero, the power being pulled through the contacts will always be the same. So if the load is 500VDC 25A it will be 500V 25A now, in 1s , in 1min, in 1hour – that is constant.

  • Overload Protection of an RCCB Or Switch in an LV Assembly to BS EN 61439-3
    Bringing power to life. Overload protection of an RCCB or switch in an LV assembly to BS EN 61439-3 BS 7671: 2018 IET Wiring Regulations 18th Edition specifies requirements for overload protection of an RCCB or switch in an LV assembly, Regulations 536.4.3.2, 536.4.5 and 536.4.202 refer. This bulletin provides BEAMA member’s guidance for RCCB and switch overload protection however; individual manufacturer’s instructions must be followed, particularly the rated current of the related assembly circuit Inc (A) which must be stated in the documentation supplied with the LV assembly e.g. distribution board or consumer unit. The rated current in the assembly circuit Inc (A) of the switch or RCCB shall be derived from one of the following two methods in diagrams 1 and 2. In both methods, circuits shall be designed so that a small overload of long duration is unlikely to occur. 1.
