Quick Distance Measurement question

When measuring the distance between a distro panel and a sub panel (to calculate correct gauge), is it measured as the crow flies or actual footage of run?

Thanks much.

I assume by "calculating the correct gauge" you are referring for voltage drop as the amps would dictate the wire size. Voltage drop is not that exact so just a measurement of the route the wire will be run is good enough.

Use your calculated load to figure voltage drop, not the rating of your overcurrent device. If there is no load, there is no voltage drop.

Re-wire 2 wire 220 outlet for a 4 wire plug

Hello, Here's my 'simple' problem. Someone gave me a washer and dryer. I already have a set. Thought I'd just put the news set on patio till I could sell. I could show they work because I have a 220 outlet there. After I rented a truck and got the appliances on my patio I remember a voice from 20-25 years ago. A repairman saw the plug and said someone used to do welding. Hmmm First step was to verify this outlet did have 220, got a tester - yep, 220. Went to store and got special 4 prong outlet needed for this dryer. Read new plug instructions. Took off old plug cover to look at wires. Looked at disconnect box. Yep - 2 wires. Only. Two wires from the double switch in the box to the outlet. No ground or neutral. This new dryer is all fancy - computer control board and so on. I don't want to fry this dryer by not having the wiring correct at the outlet! I'm not an electrician. I don't really want to be messing inside the disconnect box. My current dryer uses a 3 prong plug. I can run an extension cord for the washer to get it to work. How can I easily show this golly-gee-wiz fancy dryer works so I can sell this matched set? I've been unemployed for 5 months so I don't have much money to spend to get an electrician to make that outside plug have 4 wires for a very temporary usage? I'm open to suggestions for what I might do. Sincerely, bamakodakerRead More

Exploding bulbs

H

Hotsocket on May 05, 2015

Forum newbie but not new to electrical stuff. I have a challenge I can't answer and am hoping to get some ideas. I have two sinks in the master bath with wall mounted three-light fixtures above each sink. Never had a problem for years. About a year ago I replaced all 6 bulbs in these fixtures. The first day within hours of installing the bulbs one of them was broken: glass on the counter. I wrote it off as a fluke. Within two or three days three more exploded leaving glass on the counter. I figure the lot of bulbs were defective and returned the remaining 8 (out of box of 12). I bought some new bulbs elsewhere, installed them, and got similar results. Tried yet another brand of bulbs and got the same result. Here area few facts to add to the story: - all the bulbs I tried are 130v bulbs. I prefer these because of the long life I typically get. I had some 130v spots in the kitchen that survived 10 years of daily use. - for some reason, the center bulb in these three-light fixtures out-lasts the other two. I've gotten 4-6 weeks out of the center bulbs while the outside bulbs last a week at the most. Not years like the kitchen but better than the outside two. - I tried A15 fan bulbs and flame-shaped bulbs in the process. I thought I understood 110/220 wiring but this makes no sense to me. I would appreciate any thoughts.Read More
