- Q: I just moved into an apartment building that apparently has a chronic problem with power surges. The power tends to go on and off several times a week, for no apparent reason. I know I need to buy power surge protectors for all my equipment, but I don't know what type. I've seen surge protectors (multi-plugs) that say 875 joules, 1,045 joules, and so on, but I don't know how to translate that in terms of equipmentFor example, I have a TV, DVD Videocassette player, and high-quality music equiment all plugged into a multi-plug in the living room. Should I buy a multi-plug power surge protector for this area, and what energy requirement should that surge protector have if I'm going to plug all that equipment onto it? What type of a power surge should I buy for my computer? What about the fridge? Air conditioner? Remember, I'm probably going to need to put power surge protectors all over the place, so which would be best for the different types of equipment in a home?Thanks!!!
- If you have access to your electrical panel i.e in the apartment you may want to see if a whole house system could be installed the run around $200 US plus installation. If you can not do this, start with brand research and get specialized units designed for each type of component. Make sure the manufacturer includes a lifetime connected equipment warranty if they should fail.
- Q: I have worked there as an electrical engineer but in design for a consultant. I would like to know what are the major things to account for (DB's, wires and cables, ducts, conduits.) and how to estimate them for a typical 6000sq.ft 2 floor villa
- If you have the design drawings, you simply have to make a material take-off list. The main drawings are: General Layout Grounding Layout Electrical Equipment Layout / Schematic Riser Diagram (Fire Alarm) Lighting Layout At the very least, you need to have the General Layout drawings (to know how many rooms you've got) and you need to know the electrical levels since some houses might require 380/480 3-phase for elevators and large electrical equipment. Working room by room, you will estimate cable and conduit lengths, the number and specifications of the DBs, number of lights, outlets, switches, buzzers, intercoms, smoke detectors.

- Q: if you've heard of the wilhelm scream, is there an equivalent for an electricity crackling sound?I've heard it in Star Wars, many cartoons, probably Spider-man (it's like imagine when some big electrical equipment goes wrong and starts producing sparks, or when you have some space laser gun that stuns people).Any idea?
- I think it comes from Frankenstein, with all that electrical equipment they used
- Q: considering that he is specialised in power engineering or does he administers them.
- Electrical engineers would be primarily interested in the driven equipment namely the generators. They might be involved to a slight degree in the design of engines and turbines but not to the extent that a mechanical engineer would.
- Q: HI I need to know if anyone knows the MN electrical code for how many can lights I am allowed on one circuit using 14-2 with 15amp. also I would like to put some in my soffit outside, any type of can required for this? Thanks.
- Do the math. 15 A @120V 1680 watts. Leave some margin for heat dissipation and assume you have 1000 watts. This means you can put around ten 100 watts bulbs that are on simultanously. If you use less wattage bulbs, you can put more on it. Be careful, I noticed that if I use a dimmer, I can't put more than 5-6 lights on it because of the added heat dissipation of the dimmer. Regards
- Q: how we can design the power rating of any electrical equipment. as per my understanding only way is is to change the resistance of coil( winding if motor, filament if lamp).if it is correct then the equipment will be burn if resistance is low for low power rating. Eg. resistance of filament of 10 w lamp is lower than the resistance of 100 w. generally life of 10 w lamp is higher than 100 w. but in electrical point of view the life of high value of resistance equipment will be higher than the low value value of resistance. means, 10w bulb will glow longer time comparatively 100 w bulb. since 10 w bulb has high resistance , so this bulb's life should be higher than 100w bulb. can anyone explain how to design the power rating of any electrical equipment in line of other electrical parameters.
- The power rating of most power components and devices is limited by thermal considerations, since the life of them is a strong function of temperature. A rule of thumb is that for each 10 degrees C increase in temperature the life is cut in half.
- Q: Hey im sell a electric fencing sword wet because I just cleaned it with water because im selling it on OKorder.
- Getting any electrical equipment wet with water is a bad idea. The water hastens corrosion, and if it is still wet when it is plugged in, the resulting short-circuit can damage it and other electrical equipment further. If the weapon is an epee or foil, the barrel of the tip will hold the water and rust the spring(s) and contacts. In the future, the best way to clean a weapon is to wipe off any dirt or salt with a clean, damp cloth and dry it immediately. Use a Scotch Brite pad or equivalent to gently remove any rust or scale from the blade, being careful not to damage the wires and insulation in the groove. To keep rust off the blade, wipe the blade with a light coating of machine or gun oil, a paste wax, or silicon car wax. Keep blades away from sweaty jackets, etc. Colored blades, FIE-rated blades, and maraging blades rust less than regular steel because they are either coated with an anodyne (in the case of colored blades) or are made of an alloy that is rust resistant.
- Q: Do Aviation mechanics also work on electrical equipment and electronics on the air craft? That would be so cool if so.

- Q: If a 3 phase motor is driving a load say a gear box, compressor, or fan (Non Electrical piece of equipment) Does the load in this case gear box, compressor, or fan required a safety ground? The motor has its own safety ground
- If there is no electrical connections to them then grounding is optional.
