3 Phase-1 Phase Distribution Board RCD Test Adaptor - 10A to 50AOverview This simple 10A50A 3 phase adaptor is designed to support a wide range of electrical testing applications. It bonds L1, L2 and L3 together to allow energisation from a single phase supply, enabling RCD trip time testing from active to protective earth using a compatible portable appliance tester (PAT) or RCD tester. This makes the adaptor suitable for the testing of single phase RCD protected outlets on portable three phase worksite

Overview

This simple 10A–50A 3-phase adaptor is designed to support a wide range of electrical testing applications. It bonds L1, L2 and L3 together to allow energisation from a single-phase supply, enabling RCD trip time testing from active to protective earth using a compatible portable appliance tester (PAT) or RCD tester.

This makes the adaptor suitable for the testing of single-phase RCD-protected outlets on portable three-phase worksite distribution boards using a single-phase test supply.

In addition, the adaptor enables earth continuity and insulation resistance testing on 3-phase appliances and extension leads when used with a suitable appliance tester.

Note: This device is not capable of applying power to 3-phase appliances or converting single phase supply to 3-phase.

Applications

  • Can be used with an RCD tester with isolation* (or a suitable portable appliance tester) to perform RCD tests on single phase outlets on 3-phase distribution boards.
  • Allows testing of earth continuity and insulation resistance of 3-phase equipment and extension leads
  • In conjunction with an RCD test adaptor (sold separately) the device enables functional verification of RCD operation on portable three-phase distribution boards without energising from the fixed installation.**

*Isolation transformer sold separately

**This adaptor does not provide a three-phase supply and should not be used where AS/NZS 3760 requires testing with a three-phase supply connected (Clause H.3.2).

Capability Summary

The adaptor provides the following test capability* 

  • Earth continuity - Yes
  • Insulation resistance - Yes
  • Extension lead current leakage - Yes
  • Appliance current leakage - No
  • Polarity - Yes (L123/N only) - Yes
  • RCD Trip Time/Trip Current - Yes*
  • Loop/Line Impedance - No
  • Phase rotation/wiring - (L1-L1, L2-L2,L3-L3) - No

*Only in conjunction with suitable test instruments that have the required test functionality (not included):

Inexpensive doesn’t mean cheap.
Color: Black/Orange
After 10 months, zero complaints. Well, I got rid of the horrible NATO strap 🙄. That’s a personal preference. Easy to swap out to whatever you like. Keeps accurate time meaning it’s the same time. I’m not micro analyzing it and the seconds gained/lost. It has a confident look and feel and makes you feel good when wearing it. Sure it’s not high priced but it’s not cheap. Very comfortable, light and not unincumbered. If this is what you’re looking at, you’d be satisfied. Great looking, durable and simple watch. Full confidence.

Budget Seiko Prospex this is not
Color: Black/Orange
Bought this as a cheap work watch, but I guess all the budget went into the solar technology. No date adjust feature, gotta crank the crown over and over to adjust the date. (Also no screw-down crown, but that's expected at this price) Fake diver bezel. Lol why? Cringe as heck. Should of just put a compass bezel on there instead tbh. Cheap plastic crystal, scratches and mars just by looking at it. Okay NATO strap. Falls apart quickly, but it's easily replaceable with a better quality one. Decent lume on the hands, but none on the hour markers even though it looks like there is. Looks cool.

Simplicity
Color: Black/Orange
This watch was received exactly as advertised. First off the watch is economical compared to other watches that advertise the same details. I will say that I have gone through numerous Luminox watches only to be disappointed. This watch fits the bill. It does have solar cells which mean it needs to be exposed to light to keep running, not a problem. Three minutes under my surefire light I am golden. The bezel doesn't rotate actually no big deal for me. I have always required that the bezel moves not anymore after having a bezel that rotates I use it next to never. Here's why, the more I rotate the bezel the more the numbers wear off. The strap on the watch with the catches for the strap are perfect. They actually hold the watch strap in place in lieu of like other big name brands that just flop and slide. As far as everyday use goes this watch is my go to. To be honest I have purchased three. This is the only watch I will wear moving forward, yeah the glass my scratch but even the big names like the Luminox I spoke of earlier scratches too.
