For example, in remote areas such as deserts, mountains,&nbsp;and forests.

A 45 Amp (5500&nbsp;Watt)&nbsp;\u201cputt-putt\u201d will generate enough electricity to run several&nbsp;lamps. Keep&nbsp;in&nbsp;mind&nbsp;that&nbsp;the&nbsp;small&nbsp;Honda&nbsp;generators&nbsp;are&nbsp;not&nbsp;baffled&nbsp;&#8211;&nbsp;they&nbsp;are&nbsp;very&nbsp;noisy&nbsp;and not at all suitable when recording&nbsp;sound.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To&nbsp;determine exactly how big a generator you need you can use the formula&nbsp;\u201cWest Virginia\u201d. That is,&nbsp;W=VxA.&nbsp; Watts = Volts x Amp&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Figure that a&nbsp;1000&nbsp;Watt&nbsp;lamp at the standard&nbsp;110&nbsp;Volts&nbsp;will draw 10 Amps (divide 1000 by 100 to give yourself a 10% safety&nbsp;factor).&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Calculate how many lamps you will be using at any one time on your set. Add up the wattage and divide by 100. That will tell you how&nbsp;large a generator you&nbsp;need.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A 350 Amp generator should provide enough power to light 35 1K tungsten lighting instruments. Of course, that would be running at&nbsp;peak, which you don\u2019t want to do very often \u2013 or for very&nbsp;long. A student film will generally not need anything larger than a 500-amp generator. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&nbsp;Large&nbsp;feature&nbsp;films&nbsp;will&nbsp;often&nbsp;run&nbsp;two&nbsp;750&nbsp;Amp&nbsp;generators&nbsp;to&nbsp;provide&nbsp;enough power to light their&nbsp;sets.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With generators larger than 100 amps, power is distributed by larger cables using banded 2&nbsp;\u201cot\u201d&nbsp;or 4&nbsp;\u201cot\u201d&nbsp;Camlock connectors.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are using HMI or fluorescent&nbsp;lights,&nbsp;&nbsp;there&nbsp;are some other considerations you&nbsp;have to keep in mind.&nbsp;To&nbsp;avoid \u201cflicker\u201d your lamps must be flicker-free \u2013 or the generator must have crystal sync to&nbsp;maintain a constant 60HZ (cycles\/second) at&nbsp;24fps.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lamps larger than 10K will require&nbsp;<strong>3-phase power<\/strong>. LMU\u2019s Grip and Lighting Department does not provide any resources for 3-phase power distribution&nbsp;other than the required cables.&nbsp;You will have to rent&nbsp;3-phase power distribution boxes&nbsp;from a 3rd party vendor.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Please makes sure you check with the L &amp; G staff at the time of ordering equipment to confirm whether you need a generator.&nbsp;<\/strong>&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><mark style=\"background-color:rgba(0, 0, 0, 0);color:#ab0c2f\" class=\"has-inline-color\"><strong>GFCI<\/strong>&nbsp;<\/mark><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>We highly recommend using a Lifeguard GFCI (ground-fault circuit interrupter) with the generator.<\/strong>&nbsp;A GFCI is a device used to monitor the flow of electricity to a piece of equipment. Moisture and dampness are two of the biggest causes of ground faults, and the consequences can be life&nbsp;altering.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If&nbsp;electricity flows from hot to ground through you, the result is a ground fault, and it could be fatal. The GFCI&nbsp;can sense the current flowing through you because not all of the current is flowing from hot to neutral as it&nbsp;expects &#8212; some of it is flowing through you to the ground. As soon as the GFCI senses this &#8220;leakage&#8221; of&nbsp;power, it trips the circuit and cuts off the electricity.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>We have some GFCI devices in the Lighting &amp; Grip department. The Studio Operations Administrator will determine if you will need to rent a GFCI from an outside vendor.&nbsp; The cost is&nbsp;about $300 per week. The GFCI rental paperwork must be inspected by the Studio Operations Administrator before your Lighting and Grip order will be released.&nbsp;<\/strong>&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><a href=\"https:\/\/www.guardiangfci.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">Guardian GFCI&nbsp;<\/a><br>12685 Van Nuys Blvd.<br>Pacoima, CA&nbsp;91331<br>818-565-3550, ask for Steve Brock.&nbsp;<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><mark style=\"background-color:rgba(0, 0, 0, 0);color:#ab0c2f\" class=\"has-inline-color\"><strong>WHERE DO I GET A&nbsp;GENERATOR?<\/strong>&nbsp;<\/mark><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DO NOT get your generators and GFCIs from places like Home Depot and Lowes.

As long as&nbsp;your location is within the&nbsp;30-mile&nbsp;Studio Zone,&nbsp;this charge will be substantially less than purchasing third party vehicle&nbsp;insurance.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you need the generator at multiple locations, you will have to pay additional charges&nbsp;to have it&nbsp;moved.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><mark style=\"background-color:rgba(0, 0, 0, 0);color:#ab0c2f\" class=\"has-inline-color\"><strong>HOW DO I&nbsp;OPERATE&nbsp;THE&nbsp;GENERATOR?<\/strong>&nbsp;<\/mark><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most generators available from motion picture equipment rental houses are fully automated and relatively simple to&nbsp;operate.&nbsp;However, we highly recommend you employ&nbsp;a&nbsp;professional generator operator.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You must have a designated generator operator with direct 2-way communication to the set (i.e.&nbsp;walkie-talkies &#8211; NOT a cell phone). This person is not to be considered \u201con-set\u201d crew. They stay with the generator monitor its operation and shut it down immediately if there is a problem.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Any delivered &#8220;tow plant&#8221; generator will come with a fire extinguisher.&nbsp; Locate the extinguisher BEFORE turning on the generator and place it within easy reach, outside the genie.&nbsp; DO NOT RUN THE UNIT WITH THE FIRE EXTINGUISHER STILL INSIDE THE ENGINE COMPARTMENT OR CONTAINED ELSWHERE ON THE TRAILER.&nbsp; IT MUST BE VISIBLE AND NEARBY.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Using a generator in some locations (like the Angeles National Forest) will require that you hire a Fire Safety Officer (FSO) to be on set.
