Requirements for electricity usage at TNSP 2007
The BSAS has for the first time ever planned to provide electricity for up to 42 attendees at a cost of $3 per night per amp (or 110 watts). The system was designed by a degreed electrical engineer with a high level of safety in mind. There will be three power cords supplied by the BSAS that are yellow 3-conductor UL outdoor-rated 10-gauge copper for the first 200 feet. We anticipate the voltage available at the end of each power cord to be in excess of 110VAC under full load. If you’ve watched the price of copper lately, you will realize that the BSAS has made a substantial investment to make this possible and it will take a number of years at the present cost to break even. In addition to the electricity, the $3 will likely get you a spot on the observing field that is a bit closer to the cabins, restroom facilities, dining hall, refreshments, and speakers.
The power in each of the three long 200 foot runs is further divided up into five branches each with outdoor landscaping stakes. Up to three cords may be plugged into each stake. A total of fourteen outlets will be available on each 200-foot run. We are permitting up to 1 amp (110 watts) each on these outlets. The power is supplied by three UL-approved ground-fault circuit interrupters (GFCI’s) for safety from electric shock. The GFCI’s will be tested prior to use.
Each person requiring electricity will need to provide a 3-conductor UL outdoor-rated copper cord of no longer than 25 feet. The electrical cord shall have no conductor smaller than 16-gauge size and shall be in good repair with no exposed wires or dangling plugs. The cord shall be a bright color such as orange, yellow, bright green, etc. to be easily visible to passersby. The cord shall have a UL label that is clearly visible for inspection. Additional UL-rated cords or breakout panels may be used, but the total length shall not exceed 50 feet.
BSAS will not be responsible for persons trying to use more than the allotted power causing “nuisance tripping” of the circuit breakers. BSAS will take immediate steps to make sure the guilty party is found and that the “nuisance tripping” of the breakers is stopped. Anyone pulling more than one amp will be asked to shut something down. BSAS will make sure to point out to those other people on the same power line WHO ACTUALLY IS CAUSING THE PROBLEM for everyone. BSAS recommends that each person planning on running a computer-controlled “go-to” telescope from the electric supply also bring or purchase an uninterruptible power supply (UPS). These devices can be purchased from such places as CompUSA or WalMart for as little as $25 and will save you a lot of agony if someone has a temporary power short or is using too much power causing the breaker to trip. BSAS will provide care to make sure that the power is restored quickly, but a computer-controlled scope would need to be re-initialized each time this happens. One amp is not enough power to run ANY heater other than dew heaters. One amp is also not enough power to run most desktop computers. Nearly any laptop will run on much less than one amp (110 watts). Batteries may be used to supplement current needs and recharged in the daytime or in the cabins. If you think you need more than one amp, then by all means purchase two! The electricity usage is a bargain compared to having to worry about batteries running down.
and other important rules to observe
Light from Earth is the astronomer's enemy. In order to see faint objects through a telescope your eyes must undergo a process called dark adaptation. This adaptation takes about 30 minutes. White light from flashlights, car headlights/interior lights, in fact any light other than red, will destroy your dark adaptation in less than a second. Then, you will have to wait another 30 minutes to be fully dark adapted again. Since our goal at a star party is to see faint objects, here are a few simple rules we will ask everyone to follow.
OTHER RULES
Find a BSAS volunteer if you have any questions or need help with anything. If you can't resolve a problem, ask a BSAS member. We are here to serve you and to make your TNSP experience the best it can be.
