Individual characteristics of the bug’s bite and the person who is bitten also influence the resulting sore.
white or clear skins, shed by the nymphs as they mature. reddish or reddish-brown dried stains on fabrics due to bed bug droppings. small spots of blood from bites often dried or stained onto sheets or bed clothing. 4 o raised plaster ring skin#
papular eruptions or areas of skin with raised or flat patches that may be inflamed. small red bumps surrounded by blisters or hives. 
small red bumps or welts in a zigzag pattern or a line. a red itchy bump with a dark center and lighter swollen surrounding area. a raised itchy bump with a clear center. Other signs and symptoms of bed bug bites include: Without further irritation, symptoms typically resolve after a week or so.Īlmost all bed bug bites will produce some degree of discomfort, typically itchiness and inflammation. In most cases symptoms occur more or less immediately after the bite, but they can develop or progress over the following days as well. Others are considered hypersensitive to bites and develop more severe symptoms. Many people do not feel the bite itself or develop clear symptoms other than the dots where the bug bit and some minor, surrounding inflammation and irritation. Typically, bites tend to occur on areas exposed during sleeping, such as: 20 e.Share on Pinterest The bed bug bites may form a line or be in a zigzag pattern.īed bugs can bite anywhere on the body where there is skin. The Equipment Grounding Conductor is NOT shown on the drawing. All cable connectors are of the type that have locknuts to secure the connector to the box. The wiring method is 10 AWG MC cable with a 10 AWG grounding conductor. The circuits are tapped and continue to feed other equipment or outlets. metallic and capable of being groundedįigure 129.110 leg The minimum cubic inch capacity of the j-box (shown in Figure 129.110) you could use where circuits A17-19 (2 "hots" + a neutral") enter the box is _in?. When it is _, a raised plaster cover (often called plaster ring of maximum number of conductors permitted in an outlet box. How should outlet boxes be mounted in a plywood backboard mounted on a sheetrock wall in an equipment room Select one: a Set back not more than 4 inch b. NEC Section permits metal raceways and metal jacketed cables to be used with nonmetallic boxes provided all metal raceways or cables entering the box are bonded together, Select one a. 
Section of the NEC states outlet and device boxes shall be deep enough so that conductors will not be damaged when installing wiring devices or equipment Select one: a. 314.16(B)(4)Ĭalculating and providing the proper volume of a box is not always enough. Section of the NEC states that for each yoke or strap, containing one or more devices or equipment, a double volume allowance shall be made.
If four of these boxes are ganged together to make one 4-gang box, the total volume of the box assembly is in? Select one: a. One metal switch box has a volume of 10.5 cubic inches. The box must have a minimum volume of in? Select one: a. All conductors are 12 AWG copper THHN/THWN. Twelve "travelers" are pulled into the box along with two other circuit conductors. The box will contain three 4-way switches. An equipment grounding conductor will be pulled into each PVC.
It will have several PVC conduits connected to it. Figure 107.458 A 3-gang masonry box is shown in Figure 107.458.
