Megger DCM300E 300A Digital Earth Leakage Clamp Meter
Product Details:
Looking for a quality solution for testing Earth? With 40mm jaws, high measuring capability and able to fit in your pocket, the Megger DCM300E is the solution you need.
The Megger DCM300E Digital Earth Leakage Tester is used mainly to determine the existence and amount of earth leakage current in a circuit. Measurement leakage current is critical to electrical systems where the residual current device (RCD), also known as ground fault circuit interrupter (GFCI), frequently turns off.
Key Features:
Has four ranges: 30 mA, 300 mA, 30 A and 300 A with a 0.01 mA resolution
Enables the user to read measurements even in poorly lighted or confined places through its data hold feature.
Facilitates accurate monitoring of changes through its analogue-style bar graph that allows the operator to easily interpret rapidly changing bar graphs instead of the digital display
Prolongs battery life since it automatically turns its power off if it is not used for 10 minutes.
Has jaw opening capability of 40 mm
Further ensures safety through additional features like a tactile barrier and extra insulation around the jaw that decreases incidences of short circuits between live conductors and protects the operator against electric shock
One of the easiest and least complicated means of troubleshooting faults within a circuit since its clamp-on design does not require the operator to disassemble wirings
Is extremely handy with its pocket-size design of 64(W)x176(H)x23(D) mm and light weight of only 125g
The meter will power down after approx 10 minutes of switching on

⏱ Dispatch & Delivery Timing
We aim to dispatch all in-stock orders promptly, but delivery depends on both when you order and which service you select.
UK orders: placed by 2:00 PM Monday–Friday are usually dispatched the same day.

Orders placed after these times are processed the next working day. This means delivery may occur the following day or later, depending on the courier and service selected.
Once dispatched, your chosen delivery service determines how quickly your parcel arrives:
Standard services We use Royal Mail Tracked 24 or DHL Parcel as our ‘Standard’ services. They are not guaranteed to arrive next working day.
Premium services (e.g. Royal Mail Special Delivery or DHL by Noon) offer guaranteed delivery windows.
If your order is time-sensitive, we strongly recommend choosing a guaranteed service or contacting us before ordering to confirm availability.
Please note: For logistical reasons, we may occasionally adjust the delivery method selected at checkout. For example, smaller items may be better suited to letterbox-friendly packaging or may be at greater risk of delay or loss via certain services. We actively monitor courier and postal service disruptions—including strikes and delays—and may modify shipping arrangements to help ensure timely and secure delivery.
📅 Busy Periods & Delays
We always aim to dispatch promptly, but delivery times may be affected by:
