AC connectors
« on: August 04, 2014, 03:06:52 pm »

I was just curious which single phase  connectors people normally carry with them, for gen sets and what do you come across the most at venues with out cam-locks

We carry either 4/0, 2/0 or #2 tails to Cams.

If you are NOT considering cam locks or tails for can locks, then a California connector, 50a/240v 4 wire is pretty standard.  Most gensets have several already on the generator.

The other missing plug from the list is the NEMA 14-50P.

For a common household clothes dryer, you don't need the "L".  That's for "locking" as in Twist-Lock.

I've never seen an L14-50.  I have seen many 14-50.

The next question is what do you put after the plug?  Your list has a lot of items in it; not all of them can be handled the same way - i.e. what do you plan to do with an L5-30?

I've never seen an L14-50.  I have seen many 14-50.

The next question is what do you put after the plug?  Your list has a lot of items in it; not all of them can be handled the same way - i.e. what do you plan to do with an L5-30?

So, Nate, it might be time to take a step back and identify your actual needs for power connections; i.e. having the ability to adapt from a TT-30R into your distro might be nice, but if your power needs are such that the TT-30R won't supply your needs, then there's no use having that adapter.

So, in no particular order, you should be considering...:
- do you have a mains distro, and what connection does it need?
- do you have amp rack packs that need power, and what connections do they require?
- do you have (or need) the ability to break higher amperage/voltage services into the levels that you need?
- how often will all of these capabilities be required?

If you're just used to using a pile of 20A edisons, if you want to have 220V capabilities, well, as listed, there's several to choose from. Do you really want/need to be able to adapt anything and everything?

The most common things you will see:
- cams (on generator or at venue)
- 14-50 (at venues, maybe on a large AC distro coming from cams; this is getting more common at electrical houses who do, say, RV drive ins and need to provide multiple RV power points)
- CS6364/5 ("California Connector") on generators, at some venues

Here's what I did: I have a set of cam tails to 5 wire, with distro, that powers my amp racks, when I have 3 power available and using the L21-30 rack packs in my amp racks.

For smaller events, that just need a spider box or two, I have a pile of 50A twist feeder, and a pair of spider boxes. I built a distro that takes the CS6365 and goes into a small panel with 2- L14-30 and 2-20A courtesy plugs. (I have L14-30 input rack packs as well, and swap those out in my racks if required.) I made two adapters: 1 14-50P to CS6364, and one bare wire to CS6364. I have a selection of 50A breakers. So, I can tie into a panel if needed, or I can adapt a venue range plug into the generator twist. Or I can run off the generator with the twist lock connections. I feel better about giving a a spider box to someone at an event, as opposed to the distro.

The key is to have the minimum amount of connectors/adapters. This saves you money, as well as makes setup easier when it is less confusing. Easier to have someone else help and harder for them to screw it up. Saves weight in the AC cable trunk as well. I don't even bring all of these aforementioned adapters with me, on every event-- I pack AC as needed. "A bit extra" in case there's an unknown, but with a good advance, there should be little in the unknown category.

Thoughts?
