The goal of the Electrical Inspection Bureau is to enforce the safe installation of electrical wiring and equipment and to avoid the danger of electrical shock and fire. Inspectors work in conjunction with electrical contractors and building owners to ensure all buildings meet the City of Chicago electrical code requirements.

The Electrical Bureau is responsible for a variety of inspections. Our primary function is to inspect all electrical installations and to check that they are installed in an approved manner to ensure public safety. The Bureau responds to complaints of code violations and assures that they are corrected. We also conduct annual inspections of nursing homes, day care centers, electrical signs, and buildings defined as Public Places of Assembly. In addition, the Bureau inspects fire alarms, and life safety emergency systems in a variety of buildings and institutions, to ensure code compliance and safety.

Q: Can owners do their own electrical work?

A: No. Due to the potential for electric shock or fire hazard, only Electrical Contractors licensed by the City of Chicago can perform electrical installations.

Q: Can an owner obtain an electrical permit?

A: The licensed electrical contractor completes the required permit application, along with the supervising electricians signature and license number.

Q: Does the City's Electrical Bureau recognize T U V AMERICA as a national recognized testing laboratory?

A: The city of Chicago Electrical Inspection Bureau recognizes any nationally recognized testing laboratory listed on the OSHA website. Products bearing a TUV label would be acceptable to the city's electric inspection bureau. Please see Section 18-27-110.2 of the city electrical code for this requirement.

Q: As a tenant, who do I call if I have electrical violations that the landlord will not repair?

A: Call 311. Please give as much detailed information as possible, including a daytime phone number so that the inspector can contact you to arrange a date and time for an inspection.

Electrical regulations are found in Title 14 of the Chicago Building Code, chapters 14-8 through 14- 72. Only registered electrical contractors are issued permits to perform electrical work. Electrical work is permitted either as part of a "Building Permit" or as "Electrical Work Only".

Building Permit Applications must include a properly filled out short form Electrical Permit Application. These applications are available from the Department of Buildings website. All short form electrical applications are signed by the licensed supervising electrician employed by the Contractor. Note that the Electrical Contractor's name, address and license number should be entered on the face of the Building Permit Application in the appropriate area. Electrical plans are required by various sections within the Code. An outline of these requirements can be found on the following page. Required drawings, load calculations or letters of relief should accompany the Building Permit submittal. Relief from the Code will only be considered before a permit is issued. Jobs that require Exit/Emergency Fire Prevention review will be accepted with a receipt from FPB confirming submittal along with the required electrical drawing. Jobs requiring a Standard Fire Alarm will be accepted without drawings but must include a FPB receipt confirming submittal. Before work begins on a required fire alarm system, all reviews must be complete and a separate wiring permit shall be obtained.

Electrical work shall be permitted and inspected by the State Electrical Inspector. To acquire a permit or schedule an inspection please contact Mr. Art Hall at phone 507-951-1131 or e-mail arthall.inspections@gmail.com.

Seton Hall offers all the advantages of a large research university - a national reputation; challenging academic programs; notable alumni; state-of-the-art facilities; renowned faculty; and extensive opportunities for internships, research and scholarship - with all the benefits of a small, supportive and nurturing environment.

Key design challenges for this project included creating via the addition a new, forward-thinking physical image for the Department of Electrical and Computer Engineering, incorporating the additional building program on the highly constrained site, and planning the addition and renovations to minimize disruption to the ongoing academic programs of the Department during construction.

C.-Z.C. conceived and designed the experiment. Y.-F.Z. and D.Z. grew the QAH sandwich samples. L.-J.Z. fabricated the Hall bar devices using electron-beam lithography. W.Y., L.-J.Z., R.Z., Z.Y., Y.W., H.Y., M.H.W.C. and M.K. performed the electrical-transport measurements. K.Y., R.M. and C.-X.L. carried out the numerical simulations and provided theoretical support. W.Y., K.Y., C.-X.L. and C.-Z.C. analysed the data and wrote the manuscript with inputs from all authors.

The spin-dependent transport properties of paramagnetic metals are roughly invariant under rotation. By contrast, in ferromagnetic materials, the magnetization breaks the rotational symmetry, and, thus, the spin Hall effect is expected to become anisotropic. Here, using a specific design of lateral spin valves, we measure electrically the spin Hall effect anisotropy in ferromagnetic NiCu and NiPd. We show that the magnetization vector does not lead to a sizable anisotropy of the spin charge interconversion and spin transport parameters in materials with a spin-orbit coupling comparable to the exchange interaction.

We are locally owned and operated servicing Rotorua and surrounding areas, providing electrical services to the Commercial, Industrial and Residential markets.

The Hall effect is the production of a potential difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.[1][2]

For a simple metal where there is only one type of charge carrier (electrons), the Hall voltage VH can be derived by using the Lorentz force and seeing that, in the steady-state condition, charges are not moving in the y-axis direction. Thus, the magnetic force on each electron in the y-axis direction is cancelled by a y-axis electrical force due to the buildup of charges. The vx term is the drift velocity of the current which is assumed at this point to be holes by convention. The vxBz term is negative in the y-axis direction by the right hand rule.

The valley degree of freedom of electrons in solids has been proposed as a new type of information carrier, beyond the electron charge and spin. The potential of two-dimensional semiconductor transition metal dichalcogenides in valley-based electronic and optoelectronic applications has recently been illustrated through experimental demonstrations of the optical orientation of the valley polarization and of the valley Hall effect in monolayer MoS2. However, the valley Hall conductivity in monolayer MoS2, a non-centrosymmetric crystal, cannot be easily tuned, which presents a challenge for the development of valley-based applications. Here, we show that the valley Hall effect in bilayer MoS2 transistors can be controlled with a gate voltage. The gate applies an electric field perpendicular to the plane of the material, breaking the inversion symmetry present in bilayer MoS2. The valley polarization induced by the longitudinal electrical current was imaged with Kerr rotation microscopy. The polarization was found to be present only near the edges of the device channel with opposite sign for the two edges, and was out-of-plane and strongly dependent on the gate voltage. Our observations are consistent with symmetry-dependent Berry curvature and valley Hall conductivity in bilayer MoS2.

Dr. Irwin Jacobs, CEO of Qualcomm; Dr Jayant Baliga; Michelle Lee, Under-Secretary for CommerceThe improved efficiency gained by using the IGBT in a wide range of applications has resulted in saving more than 1.5 trillion gallons of gasoline and reducing electrical energy consumption by more than 75,000 terra-watt-hours (equivalent to not having to build 1,366 one-gigawatt coal-fired power plants). Since its invention, the IGBT has saved consumers $24 trillion while reducing carbon dioxide emission by more than 100 trillion pounds. 17dc91bb1f
