My husband and I frequently do art shows. The only electricity we need is to power six clamp-on lights, each using a 65 watt bulb. For the first time ever, we are being asked to request the type of service we need, ie up to 600 watts or 5 amps, up to 1000 watts or 8.3 amps, etc. I hate to be ignorant but I'm clueless. Do I calculate the total watts of the bulbs I'm using? Or is there a better way to ensure that I order the appropriate service?

Thank you soooo much,

Six 65 watt bulbs is 390 watts, so you need at least that. I'd go with the 5 amp service so you have a little extra should you need it. This isnt the official answer, TK will tell you more.

Ceilngfanrepair is correct.

Total the wattage of the lamps you use 6 x 65+390 watts

To arrive at the amps, divide the watts by the voltage, which is usually 120 volts.

Amps = watts/volts
Amps= 390/120
Amps=3.25 total amps

Request at least 600 watts or 5 amps to have some spare power for fan, calculator, etc.

They manager of power must add up all the vendors power requirements, and the total must be fed by a distribution system that is 25 % larger than the totla connecte4d load, if the event will operate longer than 3 hours, which we consider as "continuous" load.

The event planner must have a limited amount of power where this function will be held, and is asking all vendors for their exact power requirements , so as to be sure there is enough power to go around for all vendors.
