amps

Hello, I want to run 8 CCTV cameras and 8 motion LED lights from one 12V 20A power supply. My cameras are rated as 500ma and the lights are 850ma. I will have eight wires coming off the power supply. Each wire will be running one camera and one light. I am using a Y splitter to split the power...

Hello everyone! My childhood best friend and I will be opening a fast-casual restaurant in the next year. We have selected a location and currently in the process of figuring out gasline and waterline sizes as well as the minimum needed amps for our business to operate. Our space is...

Ontario ,Canada I've installed the following : 2 x 1000 watt, 240V baseboard heaters on dedicated circuit 240 volt dual pole breaker Logic: Total AMPs drawn = 8.33 on 15AMP circuit Used 14 /2 gage wire 80% rule means circuit (wire) can safely carry 12 AMP minimum (my heaters draw total 8.33...

I have a fairly large room, a loft in a barn that will serve as a classroom, that I am installing electrical baseboard heaters in. I am installing four 2000 watt baseboard heaters: two will be off of one 240V 30A circuit; and two off the other similar circuit. I would like to install a...

Hello, I need to run new service from my house electrical panel to the back yard pool to add a heat pump 60 amp, pool pump 20 amp, outlet 15 amp and a light 15 amp (total 110 amp) its about a 50 ft run and I found a great deal on these cables today but have to make a decision today so I need...

Up to 50FT, why does 25FT & 50FT 12 gauge cords exist? I can't think of any reason to ever need 12G cords less then 100FT. All I can guess is that 12G would produce slightly less heat than 14G at the same current draw. Maybe there's more to it other than price. Because I could just buy a 25FT...

I am looking to educate myself on what's involved with upgrading my home service from 200A to at least 400A (I live in the US) to run some very power hungry computer equipment. By my basic calculations, I am currently pulling 170+ amps continually (total watts are over 16,000). Some questions...

Hello! I have a question today about inverters. if i have a 12 volt in, 120 volt out 600 watt inverter, what is the input? is the input 5 amps or 50 amps? thanks a lot because i want to figure out how many batteries i need to do something.

Hi everyone, I'm looking for some advice here. I have a 120 amp Power Distro that I am using to power a soundsystem in a theater. I usually connect it to more than adequate amperage to work efficiently. My question is, if I only have a 100 amp circuit to connect it to, will that hurt the power...

How can I tell the amps need of this 5 hp motor?

Hello all, I have what may be just a simple question but I'm having trouble finding the answer at my locale home improvement store. I am building a new workshop behind my house and I am trying to see what gauge wire I can get away with safely as wire is costly. My situation is this, My building...

Hey all, first post. I am a novice to intermediate in terms of electrical work. I have changed out light fixtures, ceiling exhaust light combos, switches and receptacles. I have added dimmers, spliced cables and a few other things. I also have a Home Depot wiring book! :eek: So, I am having my...

Hoping someone could advise me, as I have never had to deal with this type of panel before. The service coming into the house is 100amp. The panel is a split bust with 6 double pole breakers on top with 1 of them labeled main lighting which is a 60amp breaker feeding the single pole...

(A question for UK residents; 240v,13amp; British regs.): I've never been able to fully conceptualize the difference between voltage and current. Usually, that has not been a problem, as carefully observe the normal 5 or 13amp fuse criteria, just like everybody else. The "power brick"...

My wife and I just bought a house with a 100 amp panel and we are going to upgrade to 200 amps as we want to have a hot tub put in. Our first estimate for this project came in at 3000 dollars. We asked the electrician to break down the costs and submitted as follows: 1) Install new 200 amp...

This female is trying to learn about electrical systems. NOT so that I can work on it, but to understand it better. My home has 100 AMP service. Panel box has left & right side, with 6 circuit breakers on left side and 6 on right. Some breakers are 20 AMP, some 15, some 10. I just added up...
